Aaaaah now this is becoming interesting!
Where do you guys recommend for me to look at in order to get a step further? I am a software developer with quite some experience but not so much mathematical background.
I don't mind if the entire bitcoin community would consider my new coins/fork invalid. I don't need them to agree to my approach, and I don't want to attack the original either. I am trying to use the formidable technology and thinking behind bitcoin for application in another context. In other words, it would become another parallel currency - a fork.
Thanks!!!
I think what you are really after here is your own alt-coin. Alt coins do not even attempt to communicate with bitcoin nodes. Doing so would be wasteful and probably seen as an attack (however small).
Bitcoin generally runs on port 8333. Litecoin is on 9332. So their traffic is totally separated.
