If you are using mozilla, it is essential that you install
flashblock. This prevents flash from loading until the user clicks on
it--we find that since in about 95% of cases the user does not wish to
see the flash anyway (as it is mostly advertising), this solves the
bandwidth-hogging problem and makes life better for users.

I still think you should not be running the nx server for all of your
branch offices on an ADSL link. I expect if you moved it into a data
centre you would notice a dramatic performance increase.
