Yes, that's a technical issue that would be nice to have a solution to, but the real reason this doesn't functionality doesn't exist yet (either as a stand alone program, or as part of JEmplode) no one has had the time to implement it yet.
 If the running-apps-on-drive0 problem could be solved, the rest is trivial. You could even code a complete application installer entirely in the DOS batch language with a little help from FTP.exe.
