Sadly, no. I just drove over to a Bruegger's Bagels to try it out, and it doesn't.
I'm sure I'm passing it through the router right, since I double checked it before I left. I'm using the OpenVPN GUI for windows, with the following config:
remote MYDNSNAME.com
dev tun
ifconfig 10.8.0.2 10.8.0.1
secret static.key
verb 4
This is the log, with OpenVPN continually showing "connecting"

I truncated it a bit to fit, removed some extra garbage that I don't think is germane to the problem. It seems to just hang and do nothing.
I installed it and checked "hide TUN/TAP" interface in network connections, so I can't even see that. This is really strange.
