You might want to see if you can get someone to try the Belkin Pre-N 
gear out there and see how the MIMO tech they licensed works in that 

Or, find a building around here and try it out.  I would be completely 
interested to see how it works in concrete and rebar with additional 
interference.  The office building I work in (6 floors, but more like 2 
or 3 times the size is my guess) takes over 25 802.11b 100mW  AP's to 
just barely cover -- mostly because its concrete and rebar.  Ugh.

You'll find with concrete/rebar floors that you'll most likely need an 
AP on each floor.

Alternatively, if wireless is impossible, you could use a Cisco LRE 
solution if you can convince the local phone company that putting LRE 
injectors on their network where they demarc into the building is ok. 
Cisco has gone through the pain of certifying them in some markets, so 
this might be easier than it sounds. (but, my guess is the phone company 
would tell you to go away!) The hardware is more expensive, but the 
benefit would be that its dead simple.

If the phone service is in house, this would be even easier to 
implement.  Downside, its more like ~$355/user to implement for the 
hardware. (2950 LRE switches 1x24 and 1x8, CPE equipment, and POTS 
splitter)  $20-30 less if you had your own CAT3 to run over, but if you 
ended up pulling your own cable, might as well go CAT5 and run ethernet.

On the upside, that would be 6 megabit connections (or faster) to each 
user rather than a shared wireless medium.

The 2950 isn't a router, so you'd need to hook something up to it, too.
