I only know bitparking.com where one can mine devcoin, ixcoin and namecoin together with bitcoins. Is there a way to mine even more coins at the same time?
Bitparking chooses to only merge a few coins, that is simply their choice.
for example they used to include I0Coin but do not include it now.
I merge bitcoin, namecoin, devcoin, groupcoin, i0coin, ixcoin, coiledcoin and geistgeld.
If no one is going to help figure out how to get the chunks to apply that the new database is making complicated then this could be a very very long term project. But hey the longer it takes the less new miners will be jumping into merged mining so the more coins for the rest of us eh?
