Yes, corporate firewall can be a real pain at times. Duncan does have a
point that many users (especially new ones) will not know what this is

Would it be possible to test during the installation process if
--internet2 is suitable and ask for confirmation from the user. A
message as follows may suffice 

"The installation process has detected that you might be behind a
firewall which could affect downloading of new packages. If this is
true, a modification(?) will be made."
