A warning ahead: I have no clue about the algorithms involved so if the
following is plain stupidity i apologize :-)

I'm pretty much surprised that you say that. As you obviously dealt with
both algorithms I'm pretty much sure you're right but from my native point
of view i always thought AO would be faster than GI.
First of all AO only uses a gray scale color space so it should already be
faster than radiosity which needs to calculate the brightness
for every color component seperately and secondly AO only needs to calculate
intersections. Neither lights nor surface attributes of the intersected
objects are taken into account during the calculations.
So if you just take the ordinary radiosity algorithm and cut it down to that
it should be faster, shouldn't it? Can you point out the error in my
reasoning here?

Secondly: Have you thought about using an iterative method to determine in
which direction new rays are being shot? Should save some samples too.
