It would be nice if you could set a couple of open slots for larger files say over 5mb, then serveral open slot for files under 5mb. That way you don't get completely clogged up by people downloading big stuff, and the people who want the little piddly things can get their stuff without waiting hours for an open slot.

I don't really see any advantage, since the little files (usually) are a lot more common on gnutella than big files. It's better to let people get the big files while you leave the task of uploading small files to people not sharing larger files.
