I've also seen slower (much slower) than 54Mb/s in the real-world.

Part of the reason is that this is 54Mb/s HALF-duplex, of course.  And 
all the 802.11 devices on a particular network share the RF "bitpipe", 
so to speak.  One at a time... one at a time...

Also if you mix 802.11b and 802.11g devices, the access point is 
handling that by dropping to b speeds for transmissions to b clients, 
and using the higher speed for g clients... so things get even slower. 
There's measurable overhead caused by that -- thus the setting that's 
available in the setup screens of most g-capable routers that allows you 
to lock out b clients and run "g-only".
