IOTA as lib

don't know how many LOC the current core has but a serious bounty to port the core
to C would be very usefull. many service and communication related apps out there
could benefit form a painless 'snap-in' solution.

not only for micro/nanopayments like mentioned here:

sure, adding a small com layer connecting to a remote host is a another solution
but able to run a full node, wrapped into a language/OS agnostic lib gives
any app dev much better control no matter in what lang those apps are written.
