Serious suggestion. No data rate limit and all your code should port directly.
What teensy? would this one work, http://www.pjrc.com/store/teensy.html
Yes, though the driver side on the PC would need to change a little. You'd port the firmware by choosing a suitable driver model with Teensyduino (the 'serial' mode has a maximum data rate of 12 Mbit/sec and doesn't care about the baud rate settings).
