Yes.  What I meant is that one could take an existing HTTP client and server, or create one, substituting DECnet sockets for the TCP sockets.  The protocol would work just fine that way.  You'd need to decide how to deal with DECnet packet boundaries, something TCP doesn't have (a major omission).  The simplest is to pay no attention to them, which is what I understand Ultrix "streaming DECnet" sockets to do.  An alternative would be to make use of them, for example by saying that the entire HTTP header is in one packet and the payload (if any) follows in separate packets.
