[MLB-WIRELESS] PPTP via 802.11

I am looking for security solutions for my free internet project. If my
understanding is correct, WEP only protects the network as a whole;
there is no unique encryption or login for an individual node. If you know
the password (as public access members would) then it's the same as
viewing unencrypted traffic.

Windows 98+ seems to support PPTP (VPN) out of the box and FreeBSD has a
suitable server available. Is anyone using PPTP? How secure is it compared
to WEP? Are there any MTU issues due to the per-packet encapsulation?

Using an "... over ..." solution also means that I can set things up to
allow an unencrypted backdoor for people who stumble across the AP. For
example, any direct IP access on port 80 brings up a web page with
information on how to configure PPTP settings.

L2TP looks like another possiblility.

Any experiences or suggestions are appreciated...
