Moose,

As long as you release the clutch, I can't see where you're doing any 
harm.  Most
manual Xmissions are splash lubericated so it's getting the proper 
amound of lub
for the speed.  The engine is getting it's required lub as it is NOT 
connected to the
xmission.

That said, especially going down hill, I don't think it's a good 
idea.  And I've been
told that in a lot of states it's illegal to coast in neutral to 
lights, etc.  The reason
being is you don't necessarily have "positive" control over the 
vechile.  I've done
it many times, and needed to set on the gas and forgot that it was out of gear.
Luckily, as the rpms increased and the speed didn't I realized what 
was wrong and
took my foot off the gas.  But if I had really needed to stomp the 
gas, I would
have been in trouble.

But when I've slowed down conciderably, I do quite often put the car 
in neutral and
release the clutch and coast into the light.

One other point.  Speaking of releasing the clutch, when you pull up 
to a traffic light
or have to stop for any reason, you should put the xmission in 
neutral, let out the
clutch.  Keeping the clutch depress puts  wear on the throwout 
bearing and cause
a premature failure.
