Non Client based game distributors

So I'm currently doing most of my gaming on the hoof on a cute little netbook. Which is fine except that online connections are sporadic at best which means all my Steam games are unavailable, all my Beamdog games are unplayable and all my Impulse games are unaccessible. It's a bit of a shock to have your games taken away like that when they're right there on your hard drive.

As such I have taken a vow to only use non client based sites (Gamersgate, GOG) whenever possible. Does anyone have any recommendations for good services? They're the companies I want to support in these dark constantly online DRMed days.

GetGamesGo doesn't have a client, and up to now I had no problems with it.

Amazon is clientless, as is Origin for the older EA releases.

Amazon Games aren't available 'pon these sceptered isles. Though I'm glad to hear they've gone client free. Can you redownload games from them or is it a one time download like their MP3 store?

It's unlimited download; the entire process is similar to GOG's.
