I can understand the inductor problem in their own device.  But I'm confused
by reports of other dimmers flickering during transmission of Insteon
signals.  That's what pointed me toward possible early detection of the zero
crossing in the effected devices.

Do you think the Insteon dimmers emit enough ringing onto the line to cause
other dimmers to misbehave?  Why would that happen just during transmission
of Insteon signals?  Or are the reports of other dimmers being effected of
questionable validity?
