Question on enclosures

[griz]

In the current stages of designing a multi-unit boa enclosures. The units themselves will be very similiar to the melamine ones described in previous posts. However, these units, ideally anyways, would be stack one on top of the other and also side by side with no space inbetween individual enclosures. I know that most of you are probably already asking yourselves about humidity and heat control issues. Well, that is where my questions come in. Since the side by side nature of this design will no allow for side or rear venting, can I install the vents in the front plexiglass? This would not interfere with removal of the glass and I do not see why this would not work (other than aesthetics). Also, since all of my boa's are of the same species and thus the same heat tolerances, can I simply heat this particular room to the desired temp instead of heating each individual cage? Lighting is not an issue as I have already figured that one out. Any suggestions/thoughts are greatly appreciated!
