It's still just 512 megs of RAM. I'd love to find a VPS provider that gives me like 2 gigs of RAM, and charged me by how much of that was hot during the month. It's frustrating to have to pay in advance for the maximum amount of RAM I might need.

I'd like to be able to leave processes running that might have a lot of data mapped into their address spaces, but for much of the time that data can safely be paged out to disk and not used. When I come and use the machine, I'd like to have a large amount of RAM, but when I'm not using it, I don't want to pay for it.
