I'll agree and disagree with that. The number of files you share is kinda pointless cause I could be sharing 100,000 files in no time but not be of any real content anyone would recognize or want. Though it doesn't mean I should get priority because I'm sharing a lot. Plus not everyone has a 300GB hard drive.
Although I do feel there should be a bandwidth/slot monitor. For example, you're uploading 2 files at 2kb/s cause both of them only have dialup. Though I have cable so I can be uploading at 35kb/s so the next guy COULD be started if the program recognized that. Like MXMon did for WinMX. So that's 29kb/s wasted. As default I'd have 3 slots open and if the upload bandwidth didn't exceed a certain speed, it would allow another and another till a user specified amount of slots was reached allowing max usage of your upload capabilities. That would be useful!
