Hmmm, we've deployed Netware 5 with NDS in a pure IP environment across
a WAN and seen significant traffic reductions using periodic NDS
replication over the old IPX and bindary environment they used to have.
It was not completely painless though as new servers had to be built in
a Lab environment to act as masters for each site, run through rigorous
compatability testing then deployed onsite and tested yet again over a
weekend.
Then it was an easy matter to migrate the legacy servers one-by-one to
the new true IP environment.
It depends on the existing environment and whether you are free to
implement a proper NDS IP networking model.
The co-existance method using IPX-over-IP Tunnels inside the servers is
a bad idea, use tunnels on the routers with IPX EIGRP or NLSP as the WAN
protocol to cut down on RIP and SAP traffic levels.
In most cases SAP filters should be applied anyway to stop those chatty
printers and so on.
Even think of using static SAP entries if you can get away with it
combined with filters.
