The thing I'm designing is the size of pager, hence the
lack of space.  There would also be a cost issue,
as we are looking to make 25,000 to 100,000 per year.
Cost of 100,000 4066's start to add up to real money,
especially when you only need them once (use bootloader
after program is loaded). :-)

While software might be the most expensive thing in
the Universe, it doesn't take any space...
