Not really.  At least - if you install Win95 on top of a previously
installed older version of MS-DOS, it will save your old startup files
and allow you to boot into your previous version of DOS (press F4 on
startup).  I'm not sure if Win95 will be gracious enough to do this
for OpenDOS.  I'm feeling charitable today; my guess is that it will.
However, as Tim Bird wrote, it will be a dual-boot system, you won't
actually have Win95 running *on top* of OpenDOS.

Yup.  All caveats related to using both LFN and SFN on one FS apply.

Actually, as I write, I'm getting less and less sure that Win95 will
act nicely when installed over OpenDOS.  It overwrites MS-DOS's old
IO.SYS and MSDOS.SYS with its own versions of those files.  It all
depends on how much Win95 *expects* those particular files to be
there, and how it reacts when it finds that the system files are
actually called something else.  I'm not sure any more.
