How far is the "high altar" from where the people actually sit? Is it near enough and visible enough so that the people feel part of the liturgy rather than just witnesses? When the people receive the body and blood, do they walk up to the high altar, or do the celebrant(s) bring the host and chalice to them? There seems to be some practical logistical issues that were solved by placing the altar closer to the people (usually in the crossing in cruciform shaped churches).
The question is this- what benefit does using the "high altar" provide other than some cool liturgical theater?
When the celebrant and the people are both facing the east (ad orientem), the celebrant is clearly leading the people in prayer. When the celebrant is facing the people (versus populum), it is far too easy (IMHO) to sneak in a bit of liturgical theater, rather than concentrating on what's really happening in the sacrifice of the Mass. (I attribute the emphasis on the "table of the Lord" versus the "sacrifice of the Mass" in many parishes on this)

There is an altar rail where people kneel to receive. Alternately, the priests and deacons (the ordinary ministers of Holy Communion) could carry the Body and Blood to more strategic locations outside of the sanctuary.

From what I've seen, this is not that much of a major issue in classic cruciform churches.

IMHO, as said above, it helps prevent a whole lot of "cool liturgical theater," as the celebrant is reminded that Christ is the male lead in the theater and that he, the celebrant, is in a supporting role.
Examples: you ever see as the host is consecrated, that the priest appears to offer it out to the congregation? Same with the wine as it is being consecrated into the Precious Blood? Ever notice a priest ad libbing on the Roman Canon?
If you don't like it, don't go to it. The versus populum position will still prevail at the vast majority of Masses. Just let those of us for whom ad orientem IS edifying and soul-enriching have it more readily avalable to us.
