Does the ISY have native support for X10 and Insteon? My understanding is that is needed a PowerLinc 2413S to interface with the power line.

The ISY does come in a bundle with both items included.

I had heard about the short life of these PLM modules. Is that also true of the hubs?
I have been using a CM11a interface for X10 for about 18 years. I still use my PowerBook 1400 with XTension to control my X10 switches.
