I can imagine that one reason there is no evidence of any extra
terrestrial intelligence is because it always ends up as grey goo.

The most viable solution I've heard is the idea of nano-robo-cops or
blue goo.  (Who do I credit?)  But how is it possible that blue goo
can be made more viable than grey goo?

Which form of blue goo would be the most viable?  One that protected
dna based life forms or one that just protected itself against grey
goo?

I will incorporate any good answers into Viability Changes, a 
Hypercard+STELLA based simulation game.
