Universal gateway for ZigBee devices of different vendors

Hi All,

Am working on setting up a project where I should be able to control my ZigBEE End Device(ZDO or ZED) from an IP gateway. On having a detailed study, I understood on having a setup established.

But I need to confirm if Zigbee devices from different vendors will be able communicate with each other ??

If they can communicate, can a common(generic) Gateway be used for accessing or controlling the end devices(from different vendors) from a IP network ???

Kindly lend me your suggestions !! Also, your advise on the devices already available or how to progress ???

The following knowledge base article might prove useful: http://www.digi.com/support/kbase/kbaseresultdetl?id=3519

If they are all using the same PAN ID, network stack, operating profile they they should be able to share information. As for controlling each others settings, that is a whole other thing.
