Are you referring to packet burst?  In essence, this is what 
you described(watch wrap):

http://support.novell.com/cgi-
bin/search/searchtid.cgi?/2947728.htm

It was my understanding that many folks wanted to disable this 
capability and the article makes mention of this in a note on 
the bottom:

"Note: Customers have reported that the MS Client for NetWare 
may cause high utilization on NetWare servers.. Disabling the 
Packet Burst functionality of the MS Client resolves the high 
utilization problem. According to one customer, the following 
registry edit disables Packet Burst on the MS Client:"

Still, the intent was good.

Many folks also associate sliding windows with SPX.  
Technically, that is not correct.  True windowing did not 
really happen until SPX II, which also facilitated orderly 
closure of the connection (if requested).

SPX II to be more precise.  In a way, one can regard packet 
burst as a windowing mechanism, but it was not as refined as 
SPX II (IMHO).

The real issue is why Novell missed the boat on IP.  Too 
little, too late.  I am a big fan of Novell Netware.  It is a 
rock solid NOS.  Unfortunately market share typically dictates 
what will be used.  The Beta vs. VHS wars are a prime example.

Yes, I still have a working Betamax :-)
