It *SHOULD*. The "owner" option should copy the permissions from the
device, which should have been set by the login system (this is
distribution-dependent.) If it doesn't, you may want to contact the
mount(8) maintainer.

Bullshit. They work just fine, *exactly* because they run as root.
Some people create a group "floppy" and mount gid=floppy,umask=007.

No, no, no, no, no.
It's fundamentally a broken concept. You have no protection against
anyone "stealing" your mounted media, and I WILL NOT add support for
something that is that totally and fundamentally braindead.
Finally, a reminder: AUTOFS IS NOT THE RIGHT THING TO SUPPORT REMOVABLE
MEDIA. Period. Full stop. Some people use it that way, but it's a
hack. What we need is something more appropriate, like Solaris' vold.
