Wireless Sketch Uplaod

How can I upload a sketch wirelessly, from my MS version 7 PC, to an Arduino Mega 2560 about 60 feet way in the garage, via WiFi, Ethernet, virtual USB or some other means? I can Cut, Edit and Paste code but I’m not an expert at this stuff. Is there one or more boards or boxes that can get the job done?

I meant the official Arduino forum: http://arduino.cc/forum/

I went there first and they had a couple of ideas but they weren’t quite on the mark. Then they said that they had read about a new upgrade in the works and that it had been a while back so I should do a little research. I thought that I should ask you guys since you offer so many types of shield and gadgets. I figured that you might have something or plan to have something.
