It would be a good idea to have network/internet multi-player commands to send, receive, and ask for files and transfer them. That way, multi-player maps could be customized and stored on a server without players being required to obtain the map beforehand. Also, models and sounds could be transferred to add mod-ability to an online game if a developer so desires.

Sending and receiving files could also be handled similarly to how send_skill is handled using events like EVENT_FILE_RECEIVE or EVENT_FILE_REQUESTED
