There are big machines for professional/industrial ID-0 card punching,
I've seen them on and other chinese trading sites a number
of times.  Unfortunately a bit too large for our purpose.

As for a laser cutter solution: Roh, I believe your Berlin hackerspace
Raumfahrtagentur now has a laser cutter.  Is this one capable of cutting
through the smartcard plastic?  If yes, that could be an inexpensive
solution at least for the German OsmocomBB / OpenBSC hackers...
