I have a VISTA that filters internal traffic. There is no way for me to tell which report suites have this (or any other) VISTA applied without having to contact support.
Agree with Dan on this - this should be some sort of admin console ability, to see if a report suite has a VISTA rule on it and the name of the rule.
I'd follow on and add a "VISTA Rule Repository" similar to the Code Generator repository, whereby the details of the VISTA rule (which is usually a PDF of the business logic of the rule) could reside, making it easier to keep a record of VISTA rules within SiteCatalyst.
