> -- Is the technology  proprietary ?

A serious worry with the plethora of X-10 replacements that have recently
arrived.  As long as it's backed by a lot of manufacturers, it's probably
OK.  I can see a lot of also-rans like Z-wave and Insteon falling by the
wayside if Zigbee really catches on.  The small shop technologies are
usually the first to go when something relatively standard comes along.

> -- Is the technology secure?

Is *any* techonology secure?  Unless you hire contractors and bury them in a
pit after the installation, there are an incredible number of opportunites
for security failures.  Worse, still, HA security is like any other kind.
To be effective it has to be so annoying it's almost not usable.  There's
been a lot of improvement, though.  For instance, compare the garage door
openers of today with the first remote models.
