I might be interested I might be interested in this, provided:
1. There are actual channels with regularly-scheduled shows.
2. I can watch on my TV via Roku or something similar. Multiple platforms would be best.
3. The cost is reasonable, preferably under $1/month per channel.
I think this could work for niche channels such as the old ZDTV/TechTV and the original incarnation of the Sci-Fi Channel. I'd gladly pay for access to both of these. They could even show reasonable numbers of commercials to help pay the bills.
