At its most basic, it's extremely simple in concept.

The only trick I see is that the FuseTalk administration probably wasn't intended to deal with subscribers vs. non-subscribers, so the admin interface which creates the Today page messages probably doesn't have a checkbox to indicate who the message is for. To accomodate that you would need to add a field to the today page message in the database that has a flag, then check for that flag. You could have it be a three-way switch for freeloaders, subscribers and everyone.
The issue with this is server load due to more conditional logic. Without running some tests, I don't know what that load difference would be. I don't think it would be too much since it is limited to the Today page instead of adding this kind of logic to every topic page.
I am happy to support Anandtech with my subscription, the tech forums have saved me more than that in support time. However, the speed difference isn't that big of a deal. It would just be nice to get rid of some annoying marketing aimed at other people, and maybe get a thank you. Escpecially since I still haven't been able to find the swimming pool and cabana that was part of the sales pitch.
