I believe that what you are referring to is actually a product called
TransLan (sp?) sold by Vitalink the satellite people.  They developed
it in conjunction with DEC and they use the Bridge hardware/software which
they buy on an OEM basis.  The actual software which does the adaptive
forwarding was developed by Vitalink.

The forwarding is not limited to use on a local point-to-point link, but
will also work using a satellite channel operating in broadcast mode.
Thus many Ethernets spread over the country can be made to look (logically)
like one LAN.

I'm sure that they would be more than delighted to tell you how it works
and the results of their performance tests.  They are in Mountain View,
California (near Sun, 3Com, Bridge, etc.) and their phone number is
(415)968-5465.

As usual I have nothing to do with Vitalink, I just think it is a clever
product.
