[boost] [Boost][gsoc]Intrest - big integer library

Hello all, I'd like to propose new library for boost - a Big Integer library. Boost has plenty of applications build upon it and some of them has to use integers greater that those ensured by C++ standard. What is more some of them needs even Pythonlike "unbounded" integers. What I am proposing is library implementing cross-platform library supporting such integers working as standard arithmetic type. Is it a good proposal for GSoC project and who would you recommend as a possible mentor for such project? Pozdrawiam, Kamil Witecki.
