Nice. I have a 30 year old garage opener but I don't have a remote. I know the combination because I set the DIP switches, and I think I even dug up the trasmission frequency when I looked into it a few months ago. I don't know what sort of transmission the opener wants to receive, though. Any resources you can point me to on that topic?

One thing I don't know how to do is encode information in pulses. That's why I use the record/replay method. There is probably a program that will convert a binary string to pulsed data (I believe 2ms chirps with 2ms gap between them?) but I don't know of it.

There is a little more information on the opening signal here: http://andrewmohawk.com/2012/09/06/hacking-fixed-key-remotes...
