I have added a description of the implicit routines project idea and
basic requirements for possible candidates at

https://svn.boost.org/trac/boost/wiki/SoC2014

It would also be good to have a basic idea how odeint works internally.

If you are asking about the boundary value problem I need to know more
about the idea and the methods to see wether I could mentor such a
project. So a working description would be very useful.
