I'm all for it also. Anything with an easier interface is welcome. I hate having to go upstairs, pull the CF card from my PB, bring the card downstairs, plug in into my CF adapter which goes into my PC's USB port, edit an XML file, save it, go back upstairs, plug the CF card back in to my PB and come back downstair just to add a single favorite to Hex. And before anyone says anything, I'm sure there are lot's of ways using Linux command line stuff to maybe do it remotely over the network using telnet, putty or something, but I'm sorry, I left command line garbage at MSDOS 6.22 about 11 years ago - and frankly, it's faster to go upstairs than learn a new language just for one audio/video component. Is it so hard to simply scroll to a station/podcast you like within the app and with a click of the remote have it added to your favorites list?
I'm not anti-Linux or anything like that, if I had the time I'd fool around with it and learn it just for fun, but the PB will never make to the mainstream until it gets as "easy" to use as programming a VCR (and you know all the jokes people make about that). I love my ROKU PB and my friends are really impressed by what it does, but I wouldn't dare recommend it to them because they would hate me for how technical you have to be to do the most basic things.
I'm certainly grateful that there are people like you out there doing what ROKU didn't have the foresight to do, I would just hate to see the product (and this forum) go away because they couldn't produce a commercially viable (viable being the operative word) product. The more user-friendly the product is, the more it will get used, the more it will sell, you get the picture...
