Jared - the SAVF version from Centerfield also would force a workflow change to 
some degree, although it is not too severe. You could call for pricing - it's 
more than BugBusters.

The virtual thing does look cool. How you do this depends on your QINSTAPP 
program - the traditional method was to save that program to tape in a QTEMP 
tape sequence file. The rest was various SAVxxx operations to tape. The 
difference with premastering for CDs was the API call to turn off TWERP. SAVFs 
were not part of this, unless you did SAVSAVFDTA to tape.

With the virtual optical drive, you're back to the same tape-like methodology, 
without the premastering confusion.

You could add other things to the image simply by mapping to /QOPT in the IFS - 
this is way cool - it is writable both for save operations AND for normal file 
system usage (the latter might not automatically span - have not tried). If 
your QINSTAPP is restoring SAVFs to QTEMP, you can simply save THEM there, 
being sure to use the SAVFDTA(*YES) parameter - as you know, probably. If you 
are copying from the CD - probably not - you can simply use the CPYTOSTMF to 
put them on the image.

PC stuff can simply be written there as to a normal hard drive - like InCD but 
into a normal ISO-9660 format, not that funky packet format. So it's very 
simple.

Besides, you could put the image on a server and let people download it to a 
V5R2 or later machine and put it into an image catalog on the target - or let 
them burn there own CDs from it.

BTW, if your target OS is V5R2 or later, you have tremendous compression 
options on the SAVxxx command - take a look at the DTACPR parameter.
