Re: front, back, middle...

Howard,

your considerations are very interesting.  I was making
similar speculations on a portion of what you proposed,
mainly the part related to moving rewrite before backend
selection, and generalizing back-meta to backend selection;
you are moving some steps further.  I'll have a deeper look
at your mail; however, I note that since I'm not working
at the sources with the required continuity, I'm getting
lost in this callback stuff you recently put in.  Maybe
you may try to give some deeper rationale about the changes
you're making :)

Ando.
