Well for quite some time the Arpanent provided the primary long-haul
connectivity for the Internet, and it ran X.25 during its later life
(albeit a very fine-tuned form of X.25). Back in the days when 64kbps
was fast, this worked fine.
The reality is that IP is designed to work over a mix of underlying
network technologies - that's the point.
Having said that:
using a current day telco X.25 net (64kb if you're lucky) is not a
great idea for connecting LANs together, though it could be ok for
connecting individual machines to the Internet (if it weren't for
per-packet charges)
Frame relay, on the other hand, is designed to run faster, and is a
pretty good technology.
