We have seen exactly the same behavior Smith describes.  We're deep in
a regional (5 hops away from the NSF backbone), and have found a number
of sites we could ping but could not otherwise communicate with.  In one
case (uunet), we contacted the vendor of their software (Sequent), and
the vendor agreed that a higher initial TTL was appropriate.

One more thing for the "how to write a host TCP/IP implementation"
RFC?
