Maybe once Insteon becomes mature. Right now I cannot imagine a pro installer brave enough to sell & configure Insteon. Right now HAI is not losing anything by not supporting Insteon, other than in the DIY market. Elk has an early lead with Insteon support, but I bet that was added more due to DIY requests than pro requests. And I give Elk credit for trying, but due to issues outside of their control, the Elk support is not elegant or friendly yet.
