I doubt you could work with the bandwidth of firewire
with teensy 8-bit uCs; CF would be hard enough. In the
event that an AVR can work with firewire:
1. Use SD/MMC: most AVRs have a built-in SPI
interface, which you can use directly with these
memory cards.

2. check avrgcc for a c compiler; sdcc has (will
have?) a C compiler for PIC.

3. You'll probably want to store raw data.

If it doesn't seem workable, look into more high power
boards. 68K, x86, or ARM all seem doable.
