This would be useful for smaller/Indie companies but I know for sure that IBM would not want it near them or their contractual partners. I work for IBM and they really do not like end users using their own devices, 1 bit.
Welcome to the Emerging VPN Technologies Pilot This offering is designed to address the needs for IBM's mobile users that require access from unsupported, non-windows based platforms. It provides a simple/easy method for accessing the IBM network from remote locations using desktops or smartphone devices. The current platforms supported are Mac, iPhone/iPod Touch, Linux and limited clientless SSL-based access for Windows (restrictions apply please see the Support Section for details). We will begin investigation into other platforms such as Symbian S60, Windows Mobile and Google Android. Registration is open to all IBM employees but there are restrictions on the number of users per each platform. If you are interested you should register soon as available spots will fill up fast.
