Homebrew PCBs

Sorry, but it bugs me when people jump in and say "it won't work, or 
sorry to rain on your parade"

Ok, prove to me it *** WON'T***  work.

Have you tried it and failed with every possible variation, or are you 
just reading the wiki or "How it works" and
making a global statement that hopefully true engineers won't listen too.

I sorta like innovation. When we are kids, we can do anything.
When we get older, people like tell us how we can't do things.
Funny that the innovators are usually the young ones, or still young in 
mind.

Top of my head: Find a way to localize the charges by maybe sandpapering 
or pre-ectching
for rough micro-peaks.
