You can run as many VPN connections as you want. Well practically there is 
this limitation of limited IP numbers, but hey, who is complaining ;)

I would suggest however to:

1. Look into running the app on Linux.
2. Use SSH tunnel.

If you can't do that and you have to go with VPN I assume you are talking 
something like IPSec and not something like PPTP?

In case of VPN I would sugest you do limit the encryption domains to the 
minimum and use public IP space for it as well. This will ensure you don't 
end up with two incompatible encryption domains if you are running private 
IP address space.
