At the XBMC site they have posted:
“Next up is the merge from the addons branch, the underpinning of the new addons manager (go figure) as well as the basis for the PVR frontend branch. Once finished, though still a ways out, this will add the capability of extending XBMC from the couch. No need to ssh/ftp into your box to add skins, scrapers, plugins, PVR Backends, etc.”
If they can do for the PVR frontend what they have done for my downloaded TV shows and movies I will be so psyched. Way to go team.
