Is there any technical reason I should not repartition it as something else
-- ext3 or xfs, say -- and allow executables and such?

Most people format their flash drives as vfat for interoperability,
since all the major operating systems can read from and write to vfat
filesystems. If you know you'll only be plugging it into Linux systems,
then go right ahead. As far as ownership goes, remember that [ug]ids
are stored numerically on the device, so a file that's owned by your
user on your system may well be owned by (random example) apache on
someone else's.
I seem to remember reading somewhere that one shouldn't use a
journalling file system on flash-based devices such as USB drives (i.e.
you should use ext2 rather than ext3), but I can't find the reference
right now. Can anyone clarify this for me?
