Here in the UK (and I don't believe you even need a TV license for the non-live stuff) - I have a decent ADSL connection (no, not a £2.00 a month Tiscalli line with more latency and contention ratio than you can waggle a stick at) and a couple of PS3s. They output iPlayer HD to a couple of decent sized TVs, wirelessly, perfectly.
They also play Bluray (combined with a cheap LoveFilm subscription - which iPlayer also supports the online viewing of) and all of ITV/4oD/Five's online offerings too.
Of course beside all this, if you're going to pay your £120 a year TV license, I'm also legally entitled to both Freeview and Freesat, which include quite a few channels themselves.
I've also noticed recently YouTube has started offering a lot of TV shows for free (with Ads) - guess what - the PS3 plays those too!
