And this has what, exactly, to do with multi-drop networks?

Processing power is cheaper than high speed interfaces.
Can you compress the data by a factor of 3?

I recently got a 16port 10/100Mbit Switch at FRYs for 20$,
possibly not industrial temperature range.

TI makes a number of serdes chips. 

Maybe IEEE 1399 is an option ? Upto 63 devices may be daisy chained
and the data rate is 400Mb/s.  Cable length between devices are only
upto 4.5m. It looks like one of the variants based on this core
technology should handle your requirements.

I've got no interest at all in developing an interface from
scratch.Thats why I'm asking here.
Although if it meant saving the cost of a 20 port Ethernet switch in
each machine I'd give it serious consideration.

And developing your own interface from scratch isn't?
