Main Question or Discussion Point
Is there any way to transmit USB data over the air easily?
There is, it just hasn't exactly caught on yet:.You can buy off the shelf bluetooth transceivers that will probably solve your problem, but as far as I know, there is no standard for "wireless USB."
http://en.wikipedia.org/wiki/Wireless_USBWireless USB is a short-range, high-bandwidth wireless radio communication protocol created by the Wireless USB Promoter Group.
In October 2006 the FCC approved the first complete Host Wire Adapter (HWA) and Device Wire Adapter (DWA) wireless USB solution from WiQuest Communications for both outdoor and indoor use. Since then, in mid-2007 Belkin, Dell, Lenovo and D-Link began shipping products that incorporated WiQuest technology.
