RSSTV Proposal
Just a germ of an idea right now, but another innovative use of RSS: using it to syndicate PVR suggestions. This could be cool as TiVo and TiVo-like PVRs become increasingly networked. The author, Andrew Grumet, proposes some elements in a separate namespace.
Again, very early in the process, but I'm going to keep my eye on this. And even though the answer to "Are copyrighted TV programs exchanged over the Net?" is "No", you don't have to stretch your imagination too far to envision a MythTV install pumping out an RSS 2.0 feed with the <enclosure> element pointing to a captured copy somewhere.
