I would think you have to separate features from interoperability for this discussion.
What do you really want to guarantee? I doubt any vendor is going to guarantee that they will support things like the three spatial streams that were mentioned. I'm not sure what 11n will be in the end, I know discussions of upwards of 600mbps were discussed at one point. However, even now, you buy however much of even the existing features that you want. You can buy different combinations of radios and antennae and turn on different features depending upon what you pay for and how much power you can get to the device. I would think that any guarantee (assuming that it would be legally possible) would only guarantee the existing features are interoperable with later versions of the standard. I would also think that vendors aren't going to let the IEEE come up with a version of the standard that is not backwards compatible with previous versions given the role that the WiFi Alliance has taken in building momentum towards the "interoperability is what really matters especially if it takes the IEEE forever to hammer something out" approach.

On list or off is OK- just trying to gather data for our own 11n research. Kind regards- Lee H.
