One thing that hasn't been mentioned in the list of problems to crack
is alignment for double sided resist application. I know that if you
take a piece of paper, print on it and then print the same thing on
the same side you will see some "mis-registration". I'd guess its in
the 10-20 mil range on my copier though I'm sure it varies with each
printer/copier as well as the age of the transport mechanism. My
latest inkjet (canon pixma 4000) is suprisingly good on this front so
it is possible.

I guess once we get to a working single sided application, some one
will figure out double sided.
