I'd like to see an option to close LimeWire in such a way that people who are already uploading files from my hard drive are allowed to finish what they started, but no one may begin new uploads after I've told LimeWire to shut down. The client would run in the background until the last person has finished uploading, and would then close.

Napster used to provide this option, and many Gnutella clients offer it now. I feel guilty cutting people off in mid download, but sometimes I just <i>have</i> to close the program and free up my bandwidth. I wouldn't mind letting people finish existing uploads, as long as I knew that no one else would jump in and make my wait longer.

Not hard to do this manually just set the maximum uploads to 0 in Tools => Options [Uploads] section. that way people that are connected already can finish and noone else can connect.
