Not to blow down your dream of selling a bunch of these and making a small
fortune in the process, but...

Wouldnt the data files have to be writable?
I mean unless you are going to burn them custom...

If the data files were writable, then wouldnt that blow the security that
a non writable media provides?  

Also, updates, fixes, mods would be a lot harder, since a new CD would
have to be made..

Wouldnt it be a little slower to give bug fixes (as they would have to
be on a new CD as well, and thus a little more costly)


Just a few thoughts, but I may be way off base..
