This sounds like it's getting more and more application specific.  Many
projects might not have any analog at all.  Would this not be better served
by providing a generous prototype area that can be used exactly as needed by
any project?  In other words, would you find it objectionable if the answer
is "that's what the prototyping area is for"?

That brings up the question of how much prototype area is enough.  I looked
at the protoboards we have lying around that have been used many times to
quickly implement temporary PIC projects.  The vast majority of the time,
these projects fit on one board.  The ones we use have 47 double columns,
which is a little less than 5 inches wide.  I figured 50 double columns
would be good enough for most cases, especially considering that the PIC,
power supply, RS-232 interface, and debug LEDs don't eat into that budget.
I'm figuring that 10% to 15% of projects are too big for this board is about
right.  Otherwise it would be too expensive and therefore not applicable at
the low end.  The question is how big is about right?
