Scripts to allow miners more control over blocks they make...

[randomproof]

I have an idea to add the ability for miners to control which transactions are included into the blocks they make.  Basically, I'm putting the code in main.cpp lines 3160 to 3221 into an LUA script.  Is there any interest in this?  My motivation is that as the block reward drops miners are going to rely more on transaction fees and as such they will want to be able to enforce different rules, or priorities.

Definitely, a dedicated "mining" bitcoind is one of the things that miners haven't yet optimized. There might be high demand for this in the P2pool community, if it's easy to use.
