Note that these superjupiters are in the order of several
thousand earth masses, which would imply a heck of a lot of
moons. But I suppose we ought to expect moon systems like those
we see in our solar system where a number of satellites carry a
small fraction of the total mass/momentum, and there might well
be more surprising arrangements out there.

This is a point that I've often wondered about, Martin. It
doesn't have to be the planet that hosts life or water but one
or more of its satellites. Of course Arthur C. Clarke is well
ahead of us on this point having claimed that Jupiter's Europa
might be harbouring life and I believe we have Titan as well.
