It's not like you are the first person to come up with that kind of Idea.. I personally talked to a programmer over 6 to 8 months before remotethumbs came out, about building a system very close to what RT is.
I'm not 100% sure but I could swear it was boldy I talked too about my system, if not him was someone from here on GFY with a very close name.
this was a very rough draft on the trade admin part. I was turned down by the programmer because he said it would take too long to build and he wasn't interested.
So some one wants to build a program like it and they are using yours as an example.. It's not really that big of a deal.. nothing you can do to stop them either unless they steal your code.
I will say you guys came up with a nice system but the idea is nothing original, I set it up on a very small site just to check it out and it's still running.. But IMO the thumb quality is lacking quite a bit on a good prectange of your thumbs.
