It's great that Xolox connects to a whole bunch of servers at once while downloading. but with 56k (yeah, there's still tons of ppl that use 56k!) it really bogs down the transfer speed. Maybe a suggestion would be is to let the user select how many servers they want to connect to at once. so say i want to connect to one host, and if it gets disconnected then it'll search for another one without slowing down the connection.

The number of people you try to connect to at once to download from is Max Upload Speed × 2. So if you only want to try and download from 4 people at once, set your max upload speed to 2.
