I believe Bridleman has implemented something similar. But I'm looking
for a single client -> LAN solution for bearing traffic over insecure
wireless links.

The primarily flaw with PPTP was the primer was static and could be
acquired with minimal brute force. With the stateless fix the primer is
constantly renegotiated, so the primary security problem as been
ameliorated. It isn't ideal, but it one needs to support Win9x clients
there really aren't any other options. When all my Win9x users finally
upgrade I intend to move to CIPE, given the available Win32 client. My
expirements with ipsec have proven it really hard to install, crabby
about firewalls, and inoperable on some ISPs. Of course the 2.6 kernel
might just support it out of the box, which will change my avoidance
reaction.
