Note: I plan to have kits available this summer... Stay tuned!
Step 1: Overview
1. Control RoboRealm
2. Control the Roomba via the RooStick 3.
3. Run Skype
RoboRealm (http://www.roborealm.com/) is an amazing program which is perfect for this project. It enables you, with some work, to control just about any robot. The files needed for RoboRealm to control the Roomba are here:

RooStick: It is the conversion from the SCI (Serial Command Interface) Port, or on newer Roombas, ROI (Roomba Open Interface), to USB. NOTE: Same port, different names. It is possible to create your own cord, by hacking a serial to usb cell phone cable. t.com/blog/2006/07/19/roombongle-a-roomba-usb-dongle/ Drivers for RooStick available here: http://www.silabs.com/products/mcu/pages/usbtouartbridgevcpdrivers.aspx
Skype: Skype is used to transmit audio. I may switch this up later, but for now it works.
For the webserver to work out of your home network you have to port forward 80, 8080 to your internal IP. (On an Airport Extreme, it's 10.0.1.X. On most other one's it's 192.xxx.xxx.The Webcam used is auto focus which is best for robots. (Rocketfish) If you use a regular webcam, the picture will probably be out of focus a lot. I got it for $20 off of Cowboom.com
Any LCD display, as long as it's not too heavy should work. I got an I-Ink 15" Display form Amazon that weighs about 2 pounds, and was 60 dollars.
