I've made pcbnew footprints for PLCC Sockets in the past with some
scripting. In the meantime the footprint format has changed to that
.pretty. I don't had to make footprints with such big pincounts sine
them again, but I don't think they made it simpossible to use scripting
for that at all.

The key question is whether the library semantics are compatible.  EAGLE is rather nice in the way it handles schematic symbols vs. footprints and all that.

You can select footprints corrsponding to a part in the schematic editor
for each part. What's the problem?

Not that I really need the autorouter, it isn't really all that useful.  But still, it's pretty steep for a hobbyist.  I discovered KiCAD, haven't used it yet, should give it a try.

Why is that nice? This way the pcb company has your "sourcecode".
Besides of that where is the real difference to going to
"File->Plot", Select "Gerber" and push the "Plot" Button?

That can't really be to difficult...
