I neglected to ask, what would function in a silicon based life system the way water does (would it require a simple hydrocarbon?) ... if memory serves, water and silicon are not as suited to complex chemistry as carbon and water are. Perhaps a fluorocarbon molecule of some sort would do for O2 exchange?

Tidal forces caused by a subtle change in orbit would do the trick, though the gravity of Europa wouldn't hold gases as well.
