Thanks for the pointer.  While looking through my draft copy of the
10BASE-T specs I noticed that a new section has been created called
"System Considerations for Multi-segment Networks."  This section
(section 13) looks like it is meant to cover configuration issues for
multiple hubs/repeaters linked with a variety of media.

Section 13 looks like a good place to start in answering the question
of where to find information on hub/repeater configuration that meets
802.3 specs.

This section appears to be a collection of configuration information
that has been in the specs, but hasn't been collected in one place
until now.  Also included are some handy definitions (Collision
Domain, Link Segment, Segment) and a summary of the delays for the
various network media segments that are part of the Ethernet
standards.
