As far as Phase II functionality is concerned, it is my understanding
that the only new feature of the LocalTalk drivers is the best router
algorithm. Previously, the LocalTalk drivers would use the router that
they last heard from, regardless of whether it was the most efficient
one to use. The newer drivers keep track of the number of hops to a
given net and the best way to get there.
 
Phase II AppleTalk also allows the use of the newer NBP calls, making
life easier for the programmer. The recent ADSP example in develop
requires AppleTalk 53 or later for this reason. There may be other new
programmatic features of 53 and later - this is the only one that I
can remember.
