I don't think an implementation of the LL test with a given 
multiple-precision libaray qualifies as a new development to be posted 
in a .research group. $x_i = x_{i-1}^2 - 2$ isn't terriby hard to do... 
the kicker is in writing fast squaring modulo Mersenne numbers via a DWT.

Is the original poster familiar with the GIMPS project?
