A little birdie dropped me a note that looks legit and sounds trustworthy, but I can't back it up so I'm posting this as a rumor (that I have a strong hunch is real).
It looks like there's an impending deal between Yahoo and TiVo. The Yahoo TV section will add "record to TiVo" buttons like AOL added a couple years ago to their own listings. In addition, it sounds like some sort of HME app will be launched to let TiVo users get weather and traffic maps from Yahoo.
It sounds like it will be announced very soon, so we'll see in the next couple days if the rumor was true.
update: Looks like the Record to TiVo buttons are live at Yahoo, here's their page about it. Screenshot added to this post.
