I voted before INHD and HDNet were added to the poll, but I would definitely like those added. Basically, anything in HD would be my first choice.
Among SD channels, I would like to see BBC America and the Sundance Channel.
On another programming note, I love the way Voom organizes its channels by subject matter. I hope they continue to do that as they add channels (and it looks like they can, given the amount of blank channel numbers in certain areas). DirecTV, and my old analog cable system before that, just sort of threw channels up in seemingly random order. I remember with DirecTV, if I wanted to check out the news, CNN, MSNBC, Fox News, etc., were nowhere near each other. Voom makes it so much easier to flip between similar channels until you find something you like. For me, this more than makes up for the fact that the remote has only one favorites list.
