RTP streaming/tunneling over Internet

[Chris Hallinan]

Yeah, I know how to deal with a home network that does not have a static IP
address.  That's pretty easy.  Multiple ways to get around that issue.

But I couldn't find an OpenVPN server solution for MAC.  Lots of client
solutions, tho.  I really don't want to build a dedicated Linux server just
to be able to use my MACs, which was the genesis for this project in the
first place.  No radio support on MACS - plenty on Windows and Linux.
