One of the most used solutions is to do static source NAT'ting, where 
you do a 1:1 nat of the PPTP clients. That way, the other end has no 
problems with the network and you don't have to renumber, on both sides.

With a decent setup, users het their ip through DHCP so the users 
shouldn't be your problem. The servers, that's what gives you head-aches.
