The USA Today carries an article on TiVo Mobile today, which sounds like a WAP interface to TiVo Online, but only for Verizon customers. If you forgot to record something while you're away from your home, it can be useful to send off a recording request via your phone, but cellphone interfaces tend to be slow and tedious, so doing something like record the academy awards while you're eating lunch that afternoon could take a while. Other services such as BeyondTV's online scheduler offers WAP connections as well, so it's not exactly new.
TechDirt has more on this announcement, including the point that it costs $5 per month, which sounds like a terrible idea and a way to marginalize the service to very few users.
TiVo's own press release also mentions that it won't roll out until this summer.
