I agree that this sounds really cool. I'm also in the "yes, please, serial port" camp. I haven't seen a VT100 built from ATMega's, but I recently built this VT100 that's based on a PIC32: http://geoffg.net/terminal.html - it turned out great. Serial in + PS/2 keyboard, VGA and composite video out, all driven from the PIC32's internal D/A. Only a few bucks in parts (most of the $ in the connectors).
