hopster bypass that firewall!

["K a r l i @ Y a h o o !" <karlixwilliams () yahoo com>]

Has any one come across this app called hopster, 
from my reading it allows you to bypass the firewall
to get to the IM networks among other things.

Is there a workaround to block it from working Also is
anyone aware of other apps like it.

Thanx in adv.
Karl
