That would be interesting indeed, and if the process is like most, there's a smidgen in this document, and a smudge in that one, and two smidges in this one, followed by another issue smudge there. The process has really been an evolutionary process as I understand it. You know the drill, two agencies need coverage in the same area but don't have two sites, so they go in together on one site, agreeing to share the site and some of the infrastructures. It would be interesting to see the actual MOU for the sites themselves. I heard second hand info that Charlotte/Mecklenburg is sharing some sites in SC in and around the International Trade Zone and down Hwy 49. If that's true, there's no reason that other political boundaries, geographical and human, can't be bridged. The evolutionary processes of the Palmetto system and VIPER have managed to bring together more than one set of entitites to the benefit of both. It's been a very good thing in a lot of respects, and the bean counters really like it when co-funding eliminates duplicate funding and reduces the single-responsibility costs to each entity.
