gEDA-user: Free Java/net-based autorouter, useful for pcb?

[Stefan Salewski]

Hello,

do you know
http://www.freerouting.net/
of Mr.
http://www.alfonswirtz.de/
?

Seems to be a java based, Specctra interface compatible routing
software. 

Seems to be free of costs, but not really free like freedom (not GPL).
I have no idea how difficult it would be to build a specctra interface
for pcb.

Best regards
