What does that have to do with live streams? Isn't that limited to past broadcasts? Some of us prefer to watch people we follow live, not afterwords, which I can do through my PS4 browser at least. Not to mention you can't watch past broadcasts from all streamers. The streamer must have the option to turn that off.
If your only option is a PS3, then having to watch the streams after they've been broadcast doesn't seem like the end of the World (given that live streams are not possible). I mentioned that it won't work with all streams, but unless we hear back from the OP, we won't know whether this is a viable solution for the channel(s) he's interested in (he doesn't state that he's only interested in live streams).
I know this is an old thread and I apologize in advance, but in case anyone reads this thread in the future. I wanna note you can watch twitch live streams on ps3 through a media server called Serviio. (You need to install it to your computer.) Although, if you had a computer you could just watch it on your computer. Whatever. It's possible. Get serviio, and get the twitch groovy file from this link:

Twitch developers / sony are too lazy...!!!!!!!
