no, you just have to make it bootable with install, i think.

mmm, yes, i think at least the powerup libraries, which reside on the powerup
boards, at least in their blizzard edition. There may be some others, but i am
sure you can fit them in the 1.76-1.44 = 320Ko you have left after you put the
kernel there. (and geert spoke of less than 500ko m68k modular kernels).

And remember those days when you didn't had harddisks on your amiga.

Sure, i guess at least most of it could. Maybe for some of the graphic cards
this is not the case, but people in this case just could boot from the
harddisk anyway.

Well, you just make a 1.76MB tarball, that can be unzipped/copied on the
floppy disk by the user.

Also i guess with an amiga hardware, the floppy is accesible under linux, so
you could dd it to it. At least this is the case with my 880Ko floppy.

No, you just need an amiga running amigaos or linux.

No, don't think so, not sure though.

Amiboot/apusboot is GPled (i think, but anyway, we already ship it in the
boot-floppies package) as is the kernel. The little script would be just
anything you want it to be, i guess you could GPL it also.

Sure you would not have GUI or workbench or ... but it would work.

It is easy to do (i think, will have to test though). I don't think a lot of
people will use it, but it could come in handy in some cases, i guess.

What do you do actually, you just copy all needed stuff to your harddisk and
work from there. In the case of not having a amiga partition, you just boot
into a workbench boot floppy, copy the kernel and amiboot to ramdisk, and
launch it from there.

Yes, i have it also not. 

It is worth a try though, don't you think, especially if people with it
volunteer to do it.
