I've resisted hacking my tivo for a while now.  The real reason is that I just am lazy and I haven't yet run into any hack that really jumped out at me.  Until now.  Someone's working on a way to set up a TiVo with 802.11b.  Yes indeed folks, wireless.  This would rock.  In fact, this is something I think TiVo needs to think about having as an option in the future.

I'll be watching this site for when full instructions and hardware becomes available.
