Back in the late 90's I used to abuse the assign path command with zip disks, I used to take my A4000/060 into a mates shop 2 days a week and do DTP, scanning etc. for customers who were amazed at how fast I could scan a logo to knock up a letter head or poster using adpro and pagestream 2.2 (both running at once of course while playing mp3's in the background through my masplayer, really pissed of the PC owners
)
Basically I had business, home and club zip disks, wallpapers, music, clipart, dopus5 desktop, fonts etc. all assigned with the path option. Stick a zip disk in and reboot and dopus5 came up with a custom desktop for what ever I was doing without all the clutter of having everything all the time.
Yes I've also hex edited loads of programs to change data placement also used to convert a lot of *cough* dodgy *cough* copies of german software to english...
