File Upload/Filesharing Program

I am frequently on webmaster forums, i.e. digitalpoint, blackhatforums etc.....people often share files there, but always use rapidshare, or some other upload site for sharing.....to be honest, they are FULL of ads, spam and worse.....I' sick of it! I am looking for a program that will allow a user to drag and drop the file they want to share into the program. The program will generate a url, or some sort of hash that can be copy and pasted into a forum. Users that also have the software installed, can click the link in the forum, which will load the software, connect to the uploaders PC and download the file, much like a ftp program. IMPORTNANT If possible, it would be nice for the program to seed from multiple connections from those that also have download that file (much like a torrent)......IMPORTNANT The program should have a place that will allow me to push banner ad's to the software.... This is basically a new type of file sharing program, that will drag and drop and quick connect
