You mean hosted ACE servers for RSA? Well, just in case you're not aware the SecurID for the BB doesn't have to talk to an ACE server on the other side of your BES. It can be hosted elsewhere, say at your RAS provider (lets say iPass for entertainment sake).
As far as I know no hosting company has that as a standard offering. Although I'd guess some of the larger ones like Rackspace have done both BB and ACE hosting for people. -Pk
