Uh huh. But take note that you'll have a lot of problems because DOS by
itself does not support any filenames longer than its pathetic 8.3 limit! 
And unless you're willing to hack the djgpp libraries and hack together a
replacement for MSCDEX AND the DOS network redirector, Rock Ridge
Extensions are absolutely unusable in plain DOS. Needless to say, most of
this information is undocumented, as Microsoft seems to have withheld the
whole network redirector mechanism. ISO-9660 is a foreign file system to
DOS, and the way DOS "mounts" it (to use a term from Un*x), in order that
files on it can be used, is to cause it to masquerade as a network drive.
The job of the network redirector is to make network drives look like
ordinary DOS file systems, whether they're really ISO-9660, Unix, NFS,
Macintosh, or some other weird file system. I don't know about Window 95, 
NT, OS/2 or whatever other OS, though, if they have better support.
