Actually, it's more like a web service accessible through most if not all new sony products - blu-ray players, TV's, etc. The web service includes movies, series, sports.... basically (HD)TV content on demand. It uses a basic XMB interface very similar to the PS3's menu system, which seems to hint that it may be included on PS3's, as well, in an update or two. But that's just a hint.
From how it looks, then, option 3 might be the only one where you can't get it at all (legally), so your analysis might be a bit ... reversed.
