There is a Multiplayer launcher from Gog, fairly straight forward to setup a local MP game up :)
After 30min it was still running, needs a proper run through Hamachi though.
//edit 1: tried running with hamachi, no luck. We tried it with modified configs - we got the IPXNET connect to work (the host could see my entry in his ipxnet status), but still no game. We have a botched setup though - will retry some later time (host: can't set port forwarding, i'm using DS-Lite which might be an issue [can't host])
//edit 2: tried again today, friend bought the game who has a Dual-Stack connection. It worked :) now only a longer-session test remains (no VPN, direct IPv4 connection with port-forwarding setup properly)
//edit 3: we did a ~4h session, my game sadly hanged itself two times. It seems to be a bad idea to click too furiously since i was the only one with the issue.
