The eagle CAD freeware version is restricted to 1/2 Euro size (100x80mm^2)
and two signal layers.
However I have bought a full version some time ago (Eagle 3.55) that can do
full Euro size.
I think it is possible to paste two half size layouts on one full size
pcb - however that will be only possible, if changes in the existing layouts
/schematics are done with the 3.55 freeware version.
If changes are done with the eagle 4.01 the files will no more be backward
compatible to my 3.55 full version.
BTW:
Does someone here know any real freeware / GNU-licensed PCB-CAD Software
that has comparable features to EAGLE CAD ?
(Autorouter / Autoplacement would be fine but not really necessary -
these functions in EAGLE are not very usable anyway)

The pcbs can be produced with a 300dpi printer and therefore
have relatively wide traces / rest-copper and wide isolation -
and they are single sided.

That is true.
However the question is, how necessary are the improvements ?
