NetBEUI is a very very confused term; usually meant to describe 
the LAN protocol underlying the IBM/Microsoft NetBIOS communication
verb API. 

That NetBEUI employs an addressing mechanism which identifies a
communication node as a MAC address (analogous to UAA Ethernet address
or Token Ring Adapter number) and a SAP (Service Access Point) within 
that MAC.

While there is no information in the address tuple to indicate the
WAN or "IP" path to the destination LAN, this problem may be solved in
other ways ... so it kind of depends on what you mean by
"non routable" :-)

In NetBEUI there is not a routing layer.  Instead each host is refered
to by its MAC layer address.  Because of this there is the ability to
use a MAC level bridge to internetwork two or more lans together.  In
fact this works quite well.  On token ring it also uses MAC level
source routing which some people consider routing even though it is
not at the network layer of the OSI model.

I also have heard talk of adding a network layer but do not know
if anything is available yet nor am I convinced that it is needed.
