The best thing for you to do in your situation is to make an installable form template (an .msi file). Those receiving the CD will either have already installed the template or will do so from teh CD. The forms (.xml files) made from the installed template will be looking for a URN instead of a URL -- meaning they'll be looking for the unique identifyer of the installed form template, rather than looking for a specific location where the form is installed.

Without this, every person needs to have the form template installed to the exact same location (i.e. C:\MyFormTemplateLocation). That location is saved as part of the .xml file. That's why an installable (.msi) form tempalte is better for your situation.
