Could liquid water exist on Io? Or would any water that existed there be boiled away by volcanism?

there is a 'water cycle' sort of, (but not H2O)

No way. Io has no (real) atmosphere, so any water would boil or freeze immediately. Mostly Io is very cold, but in the hotspots the temperature is far beyond the boiling point. There seems not to be much water ice anyway, unlike other Galilean moons.

No! (http://www.lsbu.ac.uk/water/phase.html)

Io's atmosperic pressure is given as 10^-8 bar or 10^-3 Pa, 6 orders of magnitde below the tripple point pressure. The ambient pressure could not support liquid water at any temperature.

Guess where the hottest spot in the solar system is located (excluding that green thing in the middle :) )?

Ok, it's Io (http://www.physlink.com/News/061704IO.cfm)
