Installation Profiles

For anyone who attended the Florida May meeting where I presented a case study on my work for ScubaDiving.com, which focused a lot on installation profiles.. well I finally posted some details on my blog on how I built it, along with some related details:

Please post comments on my blog if you have any feedback, in the interests of keeping the discussion centralized.

Where can I get a copy of the installation profile - even an incomplete copy.
I'm currently making one up for a technical community group.
