Hi kristopherjturner,
I think that you could test the following process:
https://kb.altiris.com/article.asp?article=21004&p=1 (How to install the NS Agent for Unix without assigning a GUID). The main problem to image a computer with Altiris Agent is because the GUID should be unique, so if you install without assigning a GUID, you are able to image and redistribute for other computers whitout duplicated guids problem.
Test with some machines and verify NS reports to monitoring duplicate guids.
Regards,
