restrict local cube

Does anyone know how can we prevent users from creating offline/local cube (in Excel) from our OLAP/Analysis Service server ?
Thank you.I'm almost certain that this isn't possible. There are ways that you can make it a bit more difficult, but those will only annoy your users.

If you find some way to do this, please let me know how you went about it.

No, users still allowed to perform live access but must be prevented from creating local (offline) cube which they can bring home.

I'm aware of a new property introduced on SQL 2000 SP3a named RESTRICTED CLIENT but not sure if it has anything to do with our need nor how to set it up.sql
