Has anyone found/made an OFFLINE Talent Calculator?

The reason I ask is because the wonderful company I work for has invested in very belligerent firewalls that successfully impede my efforts to come up with well-thoughtout specs on Rift ZAM. Every time I get halfway up a tree with points, I have to refresh the connection to the site, and lose the points I've already placed in a tree. It's dare they restrict my efforts in persuing video gaming information while I'm on the clock. /sigh
