CAE Licensing

Working on an upgrade for our 170 to a 270.  Running v5r1 now and it will be
the same on the 270.  In pricing out the system upgrade, I was surprised to
know that while CAE is "unlimited use"  it does have a limit of "10
concurrent users".  We have been using this setup on the 170 with 20-22
concurrent users(desktops, not sessions) since installation in 1999.  We are
not getting any licensing errors expect for a very rare occasion with WinXP
CAE desktops.  We do not get any qsysopr licensing messages.  I am told that
if license messaging or access limitations happens with the new 270, CAE
licenses are $275 each.

Can anyone tell me if I can expect the need to purchase these licenses?  I
am considering using a freeware 5250 client(recommendations?) for those
machines that do not need file transfer, etc. vs. purchasing approx $2200 in
extra licenses.  We are connecting via tcp/ip.

Not much incremental cost, I realize, however I would like to turn my
budgeted amount into hardware features not extra licenses I have been doing
without for three years, you know?

Thanks,
