The idea is to control (drive) 64 TRIACs by serial comm.
Encoding the control code seems to be no problem.
Decoding the code also seems to be no problem.
How about driving 64 TRIACs ?
I already have some designs in mind, on paper, in trashcan, etc.
Suggestions are highly appreciated.
Thanks in advance.

It's probably already on your mind or in the 'round file'
A single TX (PIC16F628A or whatever, as long as it's got a built in UART) and a few receivers (also 16F628A's, same reasoning), each one driving 8 or whatever outputs hooked up to MOC3012's (opti-iso random phase triac drivers). You still have to sync with the main's zero-crossing (if you're dealing with main power), but that could probably be handled at the TX...since I would think that zero-crossing at the TX would most likely be at the same time as all the receivers (unless they were a few miles down the road or something).
