The dolphins' distinctive whistles may function as individual calling cards, allowing them to recognize each other and even refer to others by name.

Isn't that what the Duke lacrosse players did?

This isn't news, Don Shula trained his players to do this long LONG time ago. When Shula retired, 100 percent of his players were literate and capable of speaking well.

Contrasted with the Oakland Raiders. LOL

although the assumption that they possess fully formed language has never been proved

Rather we're not smart enough to figure it out.

Yeah, but Marino didn't understand "laces out" and cost them the championship.

While diving off the coast of Cozumel some years back, we ran into a pod of about 15 to 20 dolphins. Several of them came right up to us - just barely beyond arm's reach - and spewed those clicks and whistles right at us for a minute or so (I later read that these were the "scouts" in the pod).

Anyway it was both terrifying and exciting, I was actually trying to yell at them through my respirator (strange). The diving instructor I was with said he'd never seen dolphins come so close to divers.

The aftereffects of this encounter lasted for days, and were far too odd to describe here.

A couple days later I took a jet ski out to another pod off the beach (about 100-200 yards) and had some fun with two dolphins which swam on either side of the bow, no matter how fast I went. Actually it was clear they were trying to steer me away from the rest of the pod about 25 to 50 yards further out.

That is what I think!
As a biology student I came across interesting facts concerning the brains of dolphins, which surprised me.

1) Their brains are larger then those of humans, even taking brain to body ratio into calculation.

2) Dolphin brains also have way more astrocytes. Astrocytes determine how much energy will be made available for neurons to use, modulate growth of the brain and development of neurons and have roles in associative and abstract thought. Usually more astrocytes means higher intelligence when it comes to animal species, and Einstein for instance had more astrocytes in his parietal lobes, which are involved in a.e. abstract mathematics.
Dogs have more than rats, apes more than dogs, humans more then apes, and dolphins more than humans.

3) Dolphins have a larger and more convoluted cerebrum than humans. More convulations means more surface area and is a sign of a more complex brain.

Everything points to dolphins having an astounding intelligence. If I had to point to what I thought was the most intelligent species on the planet strictly by looking at the brain, my first guess would not have been humans.

If dolphins had hands and legs, they may very well have been the dominant species. And we would be in their zoos performing tricks for bananas.

where dolphins can all see each other, they drop out of the repertoire almost entirely, replaced by other whistles with meanings that remain enigmatic.

On land, we call this "closing time."

The family dogs & parrots recognize the school bus and the Chevy S-10 'signature' and get animated & vocal cause they know the kids will be bursting thru the front door any minute. And, if the parrots are separated from one another in the house, they squawk back & forth to one another.

Not unusual because dogs, most birds and dolphins are all social creatures...packs, flocks, pods.

They are still trying to find out the name of their running back. RIIICKKY has some short term memory problems again this season, and won't respond to audibles.

I remember also about a case, where dolphins that where trained to do a trick where separated in a basin from other dolphins that hadn't learned the trick yet.

They where visually separated but could still hear eachother. Now, next day the trainers came back to train the other batch and imagine their surprise when they found out that the other group already knew the trick!

Only explanation is that they must have told eachother about what they had to do. It is not too far out, considering that they 'shout' at eachother what to do when hunting.

Probably the case. As you said, they do communicate pretty well during hunting and thus it wouldn't be too far-fetched to say that they 'discussed' the particulars of the trick with the other dolphins.

I once saw a very coordinated Killer Whale attack (they are technically dolphins not 'whales'), and the intricacy of the whole thing required a high level of communication.

...and yet the darn things STILL seem to get caught in a stupid net by tuna fishermen. So much for higher intellegence...
