I spent my evening fiddling around with my Roku box. I was amazed at how easy it is to put together a channel and I wanted to share the fruits of my labors. They are "private" channels, so they won't be listed in the Channel Store. These are very bare-bones and should be considered alpha quality channels, but they seem to work fairly well. And now that there's a template in place, building a channel from that template can be done in less than an hour. So feel free to make suggestions for new channels.
