The greatest Bluetooth security concern is with OBEX, the object exchange protocol, since it allows data to be transmitted to/from the BB across Bluetooth, which seems to be functionality that RIM is trying to avoid... Hence the lack of an IR port, which would effectively support the same data transfer functionality... Realistically, RIM seems to want to ensure that the only way to transfer actual data to/from the BB is via the TCP/IP stack (until recently, strictly through a BES).
Currently, a BES IT Policy will allow Bluetooth to be disabled completely, or only certain functions of BT to be disabled (ie, Headset Profile, Handsfree Profile, Serial Port Profile, etc). There is no reason that the "Keyboard Profile" could not be added to this policy for those corporate customers who are concerned.
BT communications are (or can be) encrypted, whether via a headset or a keyboard, so the risk of interception is probably about equal with either device (ie, very slim).
The greater possible security concern with a keyboard, however, would be "bluejacking"... Somebody taking control of your BB via their own BT keyboard. This is a non-issue with a headset, since you can't actually control
a BB from a headset.
However, devices are normally only susceptible to bluejacking due to flaws in the devices themselves, so I'm sure that RIM could build a secure solution... It might just take some more R&D time and certification to be able to justify implementing the HID profile. (For more information on various Bluetooth attacks and the devices that are vulnerable to them, there's a good article that can be found at http://www.thebunker.net/security/bluetooth.htm
All in all, I too would very much
like to see BT keyboard support on my 7290. Lack of an external keyboard is something I miss from my Palm T3.
