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.
