I want to make some floor switches to sent keyboard commands to my computer and possibly even a more ergonomic keyboard.
I did a google search and learned that the USB protocol is very hard to use and may not be possible with the Arduino but no one mentioned this idea.
Would this work? Figure out how to program a serial keyboard with the arduino, send the serial info preferably wirelessly (xbee) to a serial receiver (second arduino and another xbee purhaps) near my computer, this then connects to those simple serial to USB converters (http://usih.merchantrunglobal.com/ImageHosting/ViewImage.aspx?GlobalID=1003&MerchantID=1556&ImageID=1055&DisplaySize=-1&ListingID=684748) which connects to my computer.
Will this structure work? If so anyone know a tutorial on sending serial keyboard commands through the arduino 
?
Will it be fast enough?

Sounds good.

My Arduino communicates to my computer through USB. You have one that uses a different mechanism to communicate to your computer?
This will turn data sent from a standard Arduino to a Windows computer into keyboard strokes...
Or, I believe, an Arduino Uno can be presented to the computer as a keyboard.
Or, something like this can either use Gobetwino or can be presented to the computer as a keyboard...

I guess that depends on how fast your feet are.

you can take a look at this
http://www.obdev.at/products/vusb/index.html - its an usb implementation that works on almost any atmel chip
USBtiny - which also its an usb implementation for atmel chips
and this http://www.obdev.at/products/vusb/hidkeys.html its a keyboard implemented with the vusb
