Regarding the port difficulties- if there is a specific port difficulty you're looking to mine with when multi-algo goes live, please let me know. Port difficulties will most likely need to be adjusted and added to accommodate various mining equipment on the different algos.

OK... so to simplify things, there is now a single vardiff port for each algo, with the minimum difficulty shown. This should be good enough for 80-90% of the miners out there. Anyone that needs a special difficulty set for specific mining hardware, PM me with your requested difficulty, and I'll set a port for you.
