Does anyone know of anything like this:

being developed for the propeller?

    What are you wanting to do, perform integer math on 32, 64, 96, 128....bit integers?

    I have not heard of such an effort for the Prop and such huge numbers are not normally required. Are you getting into some crypto?

    Big Integer Math, as you correctly stated, is used widely in crypto-applications. I have seen that there is an implementation of AES for propeller, which would be the crypto-algo that I would select, but would prefer a non-fixed key, such as can be generated by a diffie-hellman key exchange -- which requires big-integer math, and an implementation of (a exp b) mod q [if memory serves] so that each end point in a session can set up a unique key to be used in the data exchange. I've used big-integer libraries on wintel systems for these purposes -- and just recently learned of the effort I highlighted in the link above -- so was just wondering if anything like this was ongoing for propeller.
