Hi simon,
See I dig this whole idea of sharewaring stuff,you don't need to convince me on that.
My problem is that I am from a middle class family in a poor country(pakistan) trying to get myself through university in a country(Sweden)which is far more expensive than I ever imagined.
About this idea of trial things, I would also like the idea very much. The only thing is that you have to give me an idea whereby my firmware will not be misused. To the best of my knowledge, without the physical transfer of an IC, it can not be done.
Anyways, I am someone who believes in trusting people. So contact me direct and we'll see if we can work something out. My address is u970070@hotmail.com.
I am willing to send you the front end EXE and the firmware hex for trial purposes, if you can give me some assurance.
