I'm not sure what to say for the DE packet performance, but another way to
address the slow login issue is to build really inexpensive servers (we're
talking not even PII) with NT Server on them, and have them operate in the
role of BDC's. Configure the registry on these units to perform their
Directory and WINS replication in the off-peak times of the day of WAN
usage, and you'll definitely see a performance increase.
This is what I did for a client that had 4 offices connected via FR with
256k PVCs/128k CIR's (it first started out as 128k PVC's/64k CIR's, but then
threw VoIP into the mix) with NT 4, WINS, Printing across the frame (special
purpose situation for batch order print-outs) and of course the 128k
connection to the Internet that all the employees immediately went crazy
over.
I too would be interested in the DE possibilities.
