Dear Claus,
I am 57, still developing s/w because too many s/w people jumped into the manager arena so not enough experienced professional are left creating new applications. (Of course my no. of neurons is smaller than the average superbright 25 yrs. old programmer, but experience helps A LOT).
I have been doing nearly everything, but in the last twenty years my field has been applied crypto with a great emphasis on the 8x51 and 8x251 MCUs.
I have been luchy enough to get old with computers, from my first IT training on IBM 360/20 in 1971 to the T-Rex SuperComp by IBM. Do not laugh, now I am reinstalling a Basic interpreter on a piece of h/w manufactured by a friend because his Customers require more frequent updates and he was so foolish to keep both the BIOS and the Appl. layer in assembler. Updates too costly = Lost Customers. (Incidentally, can you hekp?)
I can contribute to your project both by some work and by supplying a complete Crypto Manager in ASM x 8x51: I have the algos and, more importantt, the hundreds of Modes of Operation needed to practically use cryptography.
A plus: not many 8x51 system have RSA Key Generation On Board + thr Key and Pin management.
I know the USB world (no longer so well as three years ago): I am working right now in fixing the security s/w subsystem in a USB token.

What are you doing exactly?

Ciao and thank you for your attention.

P.S.1:
IBS Italia has a branch in Kansas City: I use it when some of my
fellow (US) citizens are so stupid that they refuse to buy security s/w from abroad because of the NIHS (Not Invented Here Syndrome).
Actually there are a few million people using that same crytpo s/w in Europe and US to move EUR and USD by the millions.

P.S.2:
Are you manufacturing USB tokens? I am willing to add VAR appls. and sell them, or better do as you suggest: I am no great businessman, only a good high-tech salesman (if needed).

P.S.3:
The above mentioned s/w is valued many many thousands of dollars: if you are successful I hope to get some royalties!
