I found this
and I was wondering why someone couldn't make something like that with a slightly better interface (buddy list or something) and be able to send files. That would be possible correct? Like the buddy's has a username that the user can remember, and when they double click it it inserts the ip address of that person in the box and connects. I don't know much about programming, so please correct me and explain. Thanks!
btw it is open source, so you can just add on to it and do what you want correct?
