Well it was kind of an accident. Wallets based on bitcoin 0.10.x (yes I'm looking at you MUE!) no longer have RPC commands so you can't solo mine them.
Setting up a local NOMP pool worked well though - it uses getblocktemplate.

Then I added a few more coins that I'm either invested or interested in - that are still mineable.
Diamond (DMD) was the latest addition.
Dunno why it showed up tagged as NOMP on the explorer though 

So its mainly for me to solo or occasionally hit from nicehash but others welcome to try it.
