Concern with over-all security implications
My biggest issue here is that RIM is going to allow a foreign government access to its "local" servers. At least, that is how I read this. I doubt that the Saudi government will ask RIM to pull information for them, or that it will trust in RIM giving up all of the intercepts, and demand access to the machines itself.
Once inside these servers it would almost necessarily be inside the proprietary firewall which, given proper lax security on the inside of proprietary networks or the motivated local hacker, could allow access to parts, if not the rest, of RIM's network. Once inside, it is possible, though perhaps highly unlikely, that the Saudi government could tap into the communications of other governments which are so highly entrenched in the RIM network.
Sure, a couple of "what-ifs," "maybes," and a hypothetical or two, but is that not the nexus of security?
Paris, the antithesis of security.
