	Close. First, no formal experiments have been defined in
	the WG context (to the best of my knowledge).
	
	Next, we have 4-to-4-over-6 (464), 6-to-6-over-4 (646), 
	4-to-4-over-4 (444) and 6-to-6-over-6 spec'ed and running
	in the field, so any combination of those is available for
	experimentation. Of course, any X6X (for X = 4 or 6)
	requires a 6 path between xTRs.
