Yes, this would work fine, provided your APs have the capability to talk
directly to a RAIDUS server.

If they do not, you could always use m0n0wall's inbuilt PPTP server on the
OPT1 interface, thus forcing all users to create VPNs before they're
actually able to do anything.  You can of course then use your RADIUS server
to authenticate PPTP sessions.

In fact, this might be a nice hybrid combination between public and
employee-only access.  The hotspot might allow public access to a very
limited set of ports (as described in a previous post), possibly with quite
a strict traffic limit on it to prevent the public from using too much of
your bandwidth. You could then allow employees to connect to the same
hotspot and tunnel into the "private" network from the hotspot.

One is perfectly sufficient unless you have a clear need to run services on
separate subnets.

In all honesty the wireless APs are only going to give you around 22-25mbps
maximum. I presume the NIC in the m0n0 box is a 100mbps card, so you've got
plenty of room to play with before this becomes an issue.
