No, probably not :) The increase in the buffer size to 2MB will be 
suitable for most people for the next few years. While I don't think 
statically defining things is the optimal solution it is a lot easier 
and avoids problems with the large buffer bug in older revs.

Well... If they're willing I can work on a patch to do this. However, 
there are really only two important aspects to it - understanding that 
there is no reason why you can't switch from one cipher to another when 
you rekey and locking the usage of the none cipher down properly.
