OK, I think I get it.  But I am not sure how it relates to content
delivery in the case of something like a PVR (or any other sort of
"video on demand" aplication.  ISTM that SIP is much more useful in
the event that two parties want to contact one another, real-time.

I don't really see video-on-demand as needing much more sophistication
than an HTTP GET.

Please, enlighten me if there is an aspect that I am missing.
