Hi,
The protocol you should consider building for is TCP/IP. RNDIS is the
transport that TCP/IP uses to connect to the USB devices.
As for the OEMs, there already are OEMs that have WM5 devices that use the
PPP stack instead of RNDIS. Palm offers users the option to select to sync
via PPP for example.
The way RNDIS works is that it is installed with ActiveSync 4.x. It is
actually an add-on that is part of XP and 2000. See
http://www.microsoft.com/whdc/device...IS/rmNDIS.mspx
Microsoft has not stated if RNDIS will be the protocol for future devices.
It could change.
