As always it's better to use internally generated certificates that are password protected then either passwords or certificates alone. Having said that these password protected certificates are a PITA to distribute to users and to support remotely.

I've mostly used openvpn for nailed-up connections with shared secret 
keys and separate processes per connection where the configs are trivial 
to write.

As long as the gateway does HTTP TCP keepalive the IP is kept in the table, when the connection is dropped the IP is removed.

If you are going to use a dedicated gateway you might look at clearOS 
which, I think, handles both openvpn and pptp with web setup and its own 
concept of user/certificate management out of the box.
