VPN does what EZProxy does already -- make web access appear to come 
from an on-campus address -- but for ALL web access, not just access 
that follows links from your web pages using EZProxy. This assumes 
outgoing traffic from users using the VPN will be on an IP address 
recognized as 'licensed' by your vendors, which it typically is.

If people are using VPN's and happy with it, that's actually a MORE 
reliable solution than EZProxy. Rather than tell them to turn off your 
VPN, I would ensure you have EZProxy configured not to interfere with 
it, if possible.  If they are on a VPN, and then ALSO go through 
EZProxy... it should _work_, but it'll hurt performance, as all traffic 
is effectively being sent through two proxies, for no reason. You should 
instead configure your EZProxy so when a client is on an IP Address 
recognized as the VPN, EZProxy simply redirects without proxying instead 
of double-proxying the traffic.
