And I'm going to disagree again. :-)

A repeater connects similar media types, and repeats. A bridge conencts
_dissimilar_ media types, and repeats.

You're describing a switching farbric, using spanning tree and the like 
to me, not a bridge.

My definition is much more old school. ;-) I've known it that way for 15
odd years, and I'm not gonna change just because somebody decides to use a
funkier name.

And this is _way_ off topic for here, so all else had better be taken to
email instead of list mail. :-)
