And the answer IS....

do shell script "hdiutile create -srcfolder 'sourcePath'  
'destinationPath' -format UDZO -ov" user name myName password  
myPassword with administrator privileges

This eliminates the pesky authentication dialog from interfering. The  
source and destination paths need to be converted to UNIX  
requirements using the POSIX Path function.

Format UDZO gets it to compress. -ov overwrites any existing file.
