Summary: Yes.

Maryland, Cornell, and Berkeley all have Dandelions, Vaxes, Suns,
etc. on the same ethernet cable talking mixtures of XNS and TCP/IP
betwixt themselves.  All works well.  The business about the 
Dandelion's using a slightly different ethernet spec makes a (hardware
only) difference with which tranceivers will work with which ethernet
boards, but has nothing to do with the levels of protocol above
raw etherpackets.

(Well, is there is the funny business of TCP/IP using the XNS type
field as a length field, but this is gotten around by XNS reserving
all types which are valid TCP/IP lengths).
