JP1 Remotes

I was wondering if anyone has developed, or is interested in developing the following extenders for the RadioShack 15-1935

• Toad-Tog
• Long Key Press
• Double Key Press

I have also noticed a similarity in the physical characteristics of the 15-1935, and the URC8080 and was wondering if they used the same electronics/programming? And if so, could extenders designed for the 8080 would work on the 1935?
