I saw that FIMA has announced a public website. At first glance, it seems pretty skinny on information, except the obvious bias toward interoperability:

"Most organizations would like to be able to standardize on a single Instant Messaging (IM) client on their desktop. Multiple solutions take up valuable desktop “real estate” and are costly to support. Businesses will ideally make their technology choice based on cost, functionality and existing user base at other organizations.

However, the enterprise IM marketplace is evolving very rapidly, there is still no clear winner in the IM protocol race and, as a result, there is no true interoperability between the different products (although plenty of tactical gateways are starting to be built). As a result, businesses are faced with a number of challenges, probably more so in an industry such as Financial Services, where IM is rapidly becoming the communication channel of choice due to its real-time and presence features."
