For starters, I will make a plugin command /xdmsend or something that opens a file open dialog and sends the file. After I have a working transfer I will, maybe, make it so that when u click on send file or when a file is sent is msn messenger you will get the custom download manager or something.
Well, good news! I figured out how to do file transfers and communicate between server/client sockets
Now, IMHO I should include some error-checking mechanism (CRC, MD5, SVF, or something else). Which one to use?
