redirecting instaDMG and multiple OS versions

Hello, I'm using instaDMG to create and deploy images over a network of Macs which will be making the transition from OS 10.5.x to 10.6. Is there a way, other than having two discrete instances of the program folder, to run multiple operating system images in tandem? Also, is there a way for one to redirect the program to get the InstaUp2DatePackages from a remote server? Thanks
