There is, however, something it would be awesome for : dev kits.
If I'm a multi-platform videogame developer, I don't want to have to buy dev kits of every damn system for every person in my company. They cost a fortune and it's a mess to administer. It would be perfectly reasonable to have a shared farm of devkits somewhere out on the net, you can get to them whenever you want and run your game and get semi-interactive gameplay ala OnLive.
It would be vastly superior to the current situation, wherein poor developers wind up buying 2 dev kits for their 40 person team and you have to constantly be going around asking if you can use it. Instead you would always get instant access to some dev kit in the world.
Obviously this isn't a big deal for 1st party, but for the majority of small devs who do little ports it would be awesome. It would also rock for me because then I could work from home and instantly test my RAD stuff on any platform (and not have to ask someone at the office to turn on the dev kit, or make sure noone is using it, or whatever).
