Well, yeah.   I can't imagine that anyone's done any 
real research on using it as a pressure vessel material.

That's what I was thinking.

Tell me more about the book!   That might make my
life even more geekish.   And maybe some of the
programs I write would make sense in the real world.

Can I come over and play with it?
