	Currently I am too busy with real job (doing computer programming
mostly), and hacking electronics is my leisure time project - I don't want
to go back to programming for that :). However, I can offer my students
to do some improvements to gEDA as their semestral project, if you (and they!)
are interested.  The problem is somebody would have to mentor them, and from
my experience, the results can be of varying quality: there are excellent
students, but there are also bad ones, who cause only a loss of mentor's
time in exchange for an unusable result.

	Can optimizers be applied to manually routed traced as well?
The problem is that when I manually trace something, I have some freedom
for modifying the layout. So it would be good if later the autorouter
for singal-sized paths could ask me something like "can you move this
via 100 mils to the right, please?"

	OK, I will try to route the wide paths manually, but I am probably
no match for the pcb autorouter :-)
