If all you want is the DOS Ghost client and none of the other parts of Ghost, there are many other free (and commercial) products out there that can easily handle it. To me, the strength of Ghost isn't in the client's functionality (although I admit *nothing* happens w/out a solid client.) It's the Console and secondarily the Ghostcast Server.
When I want "just ghost.exe" (and no console and no ghostcast server) functionality, I use the free DriveImage XML.
Apologies to Symantec for reference to competitor product :)
