The more I play around with Speak Freely [1] the more I like it. I spent a few hours setting up a UDP proxy server [2] on my firewall (since the Linux 2.0 kernel doesn't really support port forwarding as I found out) and while clunky, I can now use Speak Freely here at the Facility in the Middle of Nowhere.
I then got with wlofie [3] (a friend who lives in Sweden) to see if he could get it working. He did, but had a bad microphone so we couldn't talk last night, but he was able to send a sound file using Speak Freely, so it does work.
It's going to be exciting [4], doing this voice over IP thang …
