Maybe you should state at least a few details of your problem if you want meaningful advice. I like zeromq/pyzmq which is currently an optional package http://trac.sagemath.org/sage_trac/ticket/12843 Its very easy to implement various messaging patterns without getting bogged down in details

Yes, I made a typo..Thanks for realizing what I meant. However, I still think that a solution that has complex answers is OK. If you are finding the symbolic solution isn't it better to find the general solution and then deal with specific cases? I don't see what is wrong with: p = (-A)^(1/B
