I have not had time to completely figure it out yet, but you might
want to look into "rbind" mounts instead of plain bind mounts. When I
set up my chroot I bind mounted /home into the chroot, but then found
that when I mounted files from my fileserver (mounted to
/home/daniel/Remote), I couldn't see them in the chroot. (ie, "ooffice
~/Remote/foo.odt" fails with "File not Found". ooffice is symlinked to
the do_chroot script)

Unmounting /chroot/home and remounting it as "-o rbind" did the trick.
I attempted to make this permanent with a change in fstab, but it
didn't seem to work there - only when I did it manually. When I get
time I'll have another look at it and see if I can't make it work.

There is some magic to the mounting to make it work. You can
apparently do it as a "bind" mount if the original mounpoint is
"shared" (but not if it's not). There is some documentation:
http://lwn.net/Articles/159092/ .

This would also explain why you can mount /media in the chroot, but
then not see any submounts.

Hope this helps...

"reply to all" instead of "reply".)
