Why? That's already a pretty good lineup for Bluetooth, and I don't see that
current membership in the Bluetooth SIG has a major bearing on the likelihood
of using Bluetooth in the future.

I don't think the statement is that strong, especially given what it says in
the body (e.g., "likely", "if").

Fair enough, but I still think his point has some merit -- as both range and
density grow, increased interference is inevitable. When troubleshooting a
wireless problem last week I counted 17 access points.

If it does, then it will presumably suffer in the market.

All of the Bluetooth I've installed supports networking.

I respectfully disagree.
