VPN over SSL /w UDP?

Yeah, your right Ben...

I do have a mac mini I'm not doing anything with... Maybe I'll just use that
for a home asterisk gateway and trunk on IAX...   It's a core-solo,
and not that power
hungry.

The VPS provider is pretty good, though...  Only $30/month; plenty of bandwidth,
and consistent 3mS ping time to my PSTN trunking provider POP (in the
same data center, I'd assume).
The hypervm control panel is a bit buggy, but I can deal with that.
