Hi there jorari71.
It is possible with daily builds and it will be possible with 1.0 but it is really slow, I don't recommend it.
Here is an example rendered with that.
Cheers!
EDTI: BTW it is slow in any path tracer, even in any render engine I dare to say, corona is not the slowest I saw at all, but it's time consuming to get a noise clean image :)
