Of considerable interest:
Payout switching ("I want to hold coin X, convert the rest to Y") is still pretty high on the list. I've actually got a proof-of-concept working here, with what is essentially a local embedded exchange (trading coins behind the scenes with other WP users automatically) to avoid exchanges completely. But its far from release ready... Definitely could be something to set us apart though...
Of course this would require groestl algo pool to be added to wafflepool so DMD could be mined and payed out this way ...
I am currently alpha testing a private Diamondcoin NOMP pool that I have been working on ... perhaps WP could proxy to my pool once I open it to public use (1% fee) ...
Once all is good and working properly I can add other groestl algo coins to my pool on different ports.
