No, AFAIK you need a repeater to handle the collisons, etc. 

I have a 2 port repeater somewhere (2 female AUI connectors to link to 2 
transceivers), and it's remarkably complciated inside. There's a state 
machine type of thing with the state table in RAM, and a Z80 + ROM to 
boot that. Probably about 50 chips all told.
