Nah, I've just got a wicked conservative streak (literally, not
politically) verging on Luddism - and a bad case of NIH ;)

No matter how cheap processes are, I'd just never feel quite right
modelling things that strike me as "really static" with them.

At the same time, I'm a big proponent of orthogonality - parts should
interchangeable, with general rules which have only as many exceptions as
truly necessary.

Same goes for simplicity - things should be as simple as possible, but *no
simpler* (or you'll lose something valuable.)

I have been having some problems following most of this thread lately
because it does seem to be getting rather involved and in danger of being
bogged down in minutiae.  But, I probably just need to think about it
more; gimme a couple more days...
