We already do so (S_IEXEC == 00100 == user x bit).

Samba has "map archive = yes" mapping the user x bit to the archive
attribute (without a "NOT", so it's reversed wrt DOSEMU)
it can also do similar tricks for system and hidden files
(group and world x bits).

Samba does not appear to do any such mapping for directories and
always forces the "archive", "system" and "hidden" attributes
off for directories, unless (for hidden) their name starts
with a . in Unix.

Indeed it might be a good idea to make DOSEMU archive mappings
compatible with Samba, including the ability to configure in 
dosemu.conf.

Sorry for becoming a little off-topic here.
