Is there a client for windows or web based that would allow communication to blackberry messenger users?
There are more and more users in our professional environment that have used SMS or PIN to exchange messages. As the msgs get more "chatty" blackberry messenger has caught on, but when back at our PCs we tend to stop looking at the blackberry or would prefer to resort to the PC to communicate to those who are only accessible via their blackberry.
Depending on your messaging platform and BES version, you might consider implementing some type of enterprise instant messaging solution using blackberry collaboration services.
Something like Lotus Sametime or Microsoft Communicator.
