How about lots of GRE tunnels? :-)
Well PPTP is PPP over GRE, so that's basically it.
PPTP can run without encryption too if the OP really doesn't care about encryption.
The only thing I'll say in the world of using PPTP (via PoPToP) is to consider what happens when most or all of your clients reconnect at one time (network glitch, etc). This was my biggest challenge as the original configuration had PPP calling all sorts of perl scripts and such from its ip-up mechanism. The server would come to a complete crawl as 800+ of these ip-up scripts would fire off along with their associated tasks. This would result in clients timing out, links failing, etc -- the server could never "catch up".
I was recommending it based on the protocol. I did mention that I have limited deployment experience.
OUCH. All that perl could really kill the user experience.....
Almost as bad as a D-H exponentiation!
It gets even worse... whoever had set up the system first didn't now how to get the IP address correctly from a variable in the ip-up script. So what'd they do? They called grep on /var/log/messages to look for it.
You can imagine the fun this created.... :-)
