Smooth, Lucas said he fixed the compiling issues with node-multi-hashing so give it another try.
Also regarding the payments in coinbase talk. That isn't practical to do with a normal Bitcoin-based pool for a few reasons - and there are even more reasons why its not practical to do with this new cryptocurrency. Its what p2pool does and it's part of the reason p2pool has its drawbacks compared to a central mining pool.
Eligius does it too right? They don't guarantee it 100% of the time but most payments are made that way.
EDIT: To clarify how this works, the miners who contribute to mining a block don't necessarily get paid from
that block, their shares get credited like any other pool and upon reaching a minimum payment threshold their eventual payments are made using some future block's coinbase. That avoids the issues p2pool has with dust payouts vs. minimum share value.
