I've got a client needing a VPN solution for remote users.  They are
considering a Cisco VPN Concentrator but are hindered by the cost; I told
them about m0n0 and they were interested.  They currently don't require a
large number of users to access their network but will in the future.  I
found Chris' page on how to increase the number of allowable PPTP
connections through software BUT what are the hardware considerations?  How
can I calculate how many concurrent connections are possible for a given
hardware setup?  Has anyone else used m0n0 in this way?

Thanks,
Don Gray
