Should thinnet segments even be run from repeater to repeater?
I have a copy of IEEE Draft Standard 802.3 (November 1984)
specifying 10BASE2 which in the SYSTEM CONSIDERATIONS section 10.7.1 states
the following:

        10base2 segments should not be joined to more than one 10base5
        segment (i.e. 10base2 segments should exist at the periphery of
        the hybrid structure.).
