I haven't quite read through all the descriptions, but this is AWESOME! My current emergency disk feels sort of hacked together, with adding a few things like PFS and 060 libraries to it. It still crashes Amidock and once that happens workbench itself is very buggy (for example, I can rename and copy files, but if I try to open up the 'information' dialog to change icons or something, it doesn't do anything.)
This would be excellent, since I do have Poseidon and a Mediator, so If I could get an emergency disk working that got up and running all the hardware for a quick test/fix, then it'd be immensely useful!
