If properly modularized, Fresnel should allow all of these. Having all
these options seems interesting. But having so many options might also
confuse people. We will have to be careful about how we present all this.

That's the easy one.

Yes this should work. I still have to go in the details about this in
order to find out what I will support exactly w.r.t the latest changes.
I'll do that next week. Chris, do you think you will have written more
documentation by then ?

Same thing for FSL by the way. I'm overbooked with tech' talks and
meetings this week, so I'll resume working on FSL next week. Things
should go faster then, as I'll be able to devote much of my time to
Fresnel. Hopefully this will clear up what you can do with FSL (and what
you can't do).
