Aswath likes Hamachi enough to offer advice to the developers, Applied Networking.

The services provided by Hamachi is isomorphic to those provided by a VoIP system: Hamachi server is analogous to SIP proxy server; Hamachi network address is equivalent to SIP address; NAT traversal scheme is the same. Hamachi specific application routine is equivalent to a SIP client that follows SIP signaling protocol and voice codec and also provides a user interface. Cynically speaking then, Applied Networking can easily reposition itself to be a P2P VoIP provider and raise funding instantly.
