One can, of course, do what the ACSNet software did and develop a protocol
that can exploit a full-duplex link to transmit data in both directions
simultaneously. Trouble is, most of the traffic on most sites is news,
and the flow there is usually almost entirely unidirectional. Having a
bidirectional protocol won't help much for that.
I agree with Erik; for the file-transfer work that constitutes most UUCP
traffic in particular, Trailblazers clobber V.32 any day.
