I prefer non-encryption vpn. If I use openvpn, it will require more processing power than poptop. I guess creating backup server might become difficult as it works on ssl cert. cert created on server1 might not work with server2. Whereas in poptop I need to copy single file (chap-secrets).
1500 clients is quite a lot, but not hard to handle from a single machine if you select a cpu capable of doing ssl quickly. eg a power6 machine with a few cores would handle that without any problems.
If you want to stick with commodity hardware, a couple of quad core amd's should also fit right in.
