Has much thought been given to a spacecraft essentially surrounded in water to help shield radiation? Are there any technologies currently being worked on that may prove promising for shielding?

Can you put up a poll in which us listeners can vote which voice you must use during an entire podcast episode?

Thanks!

2 days ago NASA threw Casini through Enceladus' water jets and it appears to have almost the exact make-up of our oceans! (http://www.clarksvilleonline.com/2012/03/29/nasas-cassini-spacecraft-discovers-water-jets-on-saturns-moon-enceladus/)

Am I just not understanding this correctly or were you not yet aware of it? This to me makes Enceladus the MOST EXCITING place in our solar system to explore for life.
