A little sneak peek: we're currently in the process of adding GoZBrush support to Silo, which will allow you to easily send models back and forth between Silo and Pixologic's ZBrush as you work. Assuming we can get over a final few tricky implementation hurdles, you should see this update quite soon. Silo and ZBrush have always made an ideal pairing, and GoZ support will make them even better.

You can read more about GoZ over on Pixologic's site here: http://pixologic.com/zbrush/features/GoZBrush/

Cheers!
