the hidden node problem is in Ad-hoc mode, where A can see B and A can see
C, but B and C can't see each other. It becomes a problem of packet timing
and collisions. According to the IEEE, 802.11 has something to handle this,
but can only handle up to about 10% of nodes being hidden during heavy
usage, more than that and performance will start to suffer.

some AP's have user limits, but otherwise, as many as the bandwidth can
handle

the problem with using AP's for this is that AP's can't connect to other
AP's (unless they're bridges, but that's a whole new mode all together)
