Topics from meeting (October 25th)
Created a list of all things that need to be interfaced with the processor and what kind of interface each one needs:

Wireless Transceiver
Our choice of camera will impact what kind of bandwidth our wireless transceiver will need to handle . We determined that most image sensor cameras output too much data to be sent usefully over the internet (wireless transceiver can handle a max of 1 Mbit per second UART, but also has a 44MHz clock and SPI - so any reasonable data rate could be handled. A 640x480 color image from one of the cameras we looked at will produce about 16Mbits per second at 30 frames per second.) . We tried to figure out a way to either interface an IP camera to our website or reduce the amount of data coming from a camera. This will have to be done using MJPEG compression.
