If you are ready to spend real bucks on that, I can recommend you 5DTV, http://5d.com/. They serve Canadian national networks and provide satellite uplink.
For sharing, you can try upload services like Google Video or DivX Stage6 at http://www.divx.com (the latter provides better quality, but takes forever to upload).
