John,
The system runs on 44-net addresses only. German stations are linked by high speed wireless, independent from the Internet. Outsiders, like Waldek and myself use dedicated p2p links to that network. So it has actually nothing to do with the UCSD gateway or the generic tunneling system (but it works via the IPIP tunnels, too).

The question is, are you only connecting endpoints that are using the Net-44 addresses or are you going through amprhost (UCSD) out to IP addresses on the general Internet?
If you are using Net-44 only addresses and tunneling then you might get decent latency and jitter numbers -- I suspect not if it must pass through amprhost to and from some address outside of Net-44.
