Imagine that, an 'addon'* to Steam, you could basically automate the whole process. Mark games you didn't 100% need to have around all the time as sellable, so they'd go into the 'cloud' of buyable games. Whenever you wanted to play a game, if you still owned it fine, if you didn't it would attempt to buy it for you. Every game is traded for $1 automatically. To bypass credit card pain you could either put money into your account in one go (add $20 for 20 games at one time) or just use your current steam account-- if you have 100 games that $100 right there. I have hundreds of games gotten cheap off steam sales, and games I never play anymore. I imagine at any one time there would be 1 or 2 games that I would mark as "don't sell this", but the rest would be fine. *I say 'addon', Steam obviously wouldn't want it, so it would have to be another frontend to your steam library that managed the whole process.
