RFC-38 is authored by Stephen M. Wolfe of UCLA, and is a reply to RFC-36.
The technical content
Wolfe proposes that it might make sense to allow multiple connections to share the same physical link, especially if a single computer requires multiple connections to get some work done. That way a whole bunch of physical connections won't be hogged by one computer. He also says that it might be useful in another high-traffic situation where an entire new internal network (multiple HOSTs with multiple users) connects to ARPANET and needs to connect out to the rest of the network.
He then proposes some minor additions to the new network protocol that wouldn't allow multiple shared connections in and of themselves, but would make it possible in the future. He also asks a question about whether certain situations require referencing the physical link or the software connection.
