Rick Adams of UUNET has pretty much said as much.  It may depend somewhat
on details, but the fact is that X.25 is an expensive way to ship bulk
data:  the connect charge does not look that high, but the per-packet or
per-byte charges get nasty for bulk transmission, and the throughput is
not that good.  A Trailblazer link after midnight is a pretty cheap data
pipeline.
