Current system

• A low-cost start. Whatever CPU I have on hand.
• Power, weight not so big a concern. Flexibility is, since I don't have a firm idea of hardware requirements.
• A platform for exploring applications, microcontroller interfacing, and to gauge interest.
• MPEG encoding of a single camera, if possible.

Future systems

• Highest CPU power available then
• If going for a low-weight car, then as low-weight and low-power as practical.
• Highest data-rate wireless-network available
• More navigation inputs (GPS, compass, accelerometer, optical mouse)
• Processing and encoding of multiple video streams.
• Explore DSP programming
• Camera / radio antenna aiming
• Higher reliability / uptime (start taking over semi-critical functionality)
