Hi,
This sort of thing could definitely be useful!
In reply to your questions:
1. An A1000 will only boot Kickstart from the internal drive, and as far as I know, the 1.x Kickstarts will only boot Workbench (or anything else) from the internal drive. 3.x (and possibly 2.x) will check all floppy drives for bootable disks
2. The connectors are different (34-pin IDC internal ribbon vs 23-pin D-type external). External drives have additional logic whereas internal drives just plug straight in
3. Yes, this would be of use to other Amiga owners! See
tnt23's floppy emulator for a project with a similar aim
