That's right. ID do it as follows:
- get a server machine somewhere on the internet (your home, your
office, or some VPS hosting somewhere).
- run an OpenVPN server on that server.
- setup OpenVPN clients on your two UMTS-connected machines to connect
to your server.
- you can now talk via UDP over your very own VPN network at will.
OpenVPN can run over UDP or TCP as well, and over any port (including
443), so you don't need any "passthrough" support from the NAT (IOW it
works over any NAT). And it's rock-solid in my experience.
