Stumble over this when looking for something else (as usual…);

He´s got his Mac 512k sharing files on the network/internet via a OS X machine which is forwarding the original share. This could perhaps be a viable way of loading stuff from MG onto 'The Real Deal'.
As the oldest machine I´ve got is a LC (equipped with a network card) stuffed away in the basement I can´t try this out for real. Anyone care to take a beat and share their experiences. And screendumps…
