I have emailed them...no reply. I have messaged their twitter page, and they said that they'd look into it. In my experience, the people who run the twitter feed reply very quickly to all messages. I would say to start bombarding them requests for the channel.
As for finding a carrier that has it, I'm kind of out of options. If I were to go to cable, they don't have it. Direct doesn't have it but is planning to offer it in 2010....I would expect their customers will be pushing for it as well since SEC football will be on it.
