Direcway has been around for years.
I'm told that Direcway is Starband, though I've never tried to confirm it.
Starband is either partially or fully owned by Echostar (DISH Network), I haven't kept up with their biz dealings.
DirecPC has been around for about 10 years. I did my first install in the spring of 1995. DirecPC required you to connect via land line. All your uploads went via modem, while the downloads were routed back over satellite
DirecWay has only been with us for a few years. It's the consumer version of the VSAT service and offers satellite uploads as well as downloads.
I worked for an electronics company when DirecPC was first launched and we distributed DirecPC. I spent a lot of time on the bleeding edge of this launch and at one point used to get customer support calls sent to me when the DirecPC support folks didn't know the answer.
