What's underneath that room? It may not be all that big a deal to move the water supply over (even if it is tiled), or to move it up into the wall. With the right tools, it's probably less than 10-minutes to make a nice clean hole through tile and the subflooring, then, moving the pipe may or may not take awhile, but with good access, it's not a huge job.

i went with the peerless (form over function). it fits the space. i will admit it shows the signs of a cheap company: plastic handle, no installation instructions. however, it is still a lo-low toilet (1.6) and it doesn't run. i see this as an opportunity for data collection; i will check in over the next year and let y'all know if its still working. it could be that it doesn't last, it could be that it turns out to be just fine...
http://www.peerlesspottery.com/toilet_independence.html has the more common same-bowl-different-tank. The description says "Made possible, in part, by the 1st fully automated pressure cast bowl machines in the U.S." Are they new machines, or did they pick up vintage machines? :-)
