I found this thread as I too was looking for a bootable ISO image of ElCap as I am a bit of a VM guy myself. Sudo drutil burn /Users/YOURNAME/Desktop/El\ Capitan.iso Mv /tmp/El\ Capitan.cdr ~/Desktop/El\ Capitan.iso

Hdiutil convert /tmp/El\ Capitan.sparseimage -format UDTO -o /tmp/El\ Capitan Hdiutil resize -size `hdiutil resize -limits /tmp/El\ Capitan.sparseimage | tail -n 1 | awk ''`b /tmp/El\ Capitan.sparseimage

SHEEPSHAVER YOSEMITE CODE
Here's the code anyway.Maybe someone else can tweak it to make it work. The reason being that during the installation,toward the end of the boot process it freezes. It seems there was code that was included in the O/S to dissuade the creation of optical discs though.
