Nothing wrong with transmission (except that it doesn't work with one tracker with flexget, I get error: data lost). As to VoIp services, yes there are lots of different ones but none of them are $30 a year.
I could probably get MJ Plus which is a standalone VOIP box, but it wouldn't be fun getting it to work then.
As I said, it's purely for fun and it isn't a big deal. I bet noone runs windows 98 in qemu which I installed for fun as well
