Well, I think things can be more or less cleanly done, or done 
differently (separate files, runtime selection, single huge function 
with #ifdefs)

I'm just saying, let's not create a generic plugin architecture or 
something ;-) it's really not that much code in question.

Unless you cache the separate process result I think it'll be on the 
slow side... potentially called once per message, no? Not that anything 
using this is necessarily time-critical right now.
