I added photons, changed some things and this is the result. I'm currently
rendering a radiosity version (without photons and no focal blur) but I have
no clue when that one is finished. I guess it's gonna take one or two
days...

Reflections and focal blur looks fine but ... this key looks too sharp, too
clean, too perfect. Is this csg ? If yes try rewrite it as iso_csg (with
rounded version if possible), then add some treshold and displace surface. Of
course it will slow down your render but since you plan to build "Very power
efficient cpu" as announced at off-topic... :-)

Hey, that's looking pretty good. The key still looks like plastic,
however. What finish values are you using?

Honestly, I'm not crazy about it. The key needs more of a texture for one
thing... it looks very plastic. I'd expect it to have small dents in it, and
not perfectly sharp edges (though I know how hard it can be to get rid of
those).
Also, the focal blur really hides a lot of the detail at the far end.
I think you could do more with this.

It's getting VERY good! However, IMHO, if you want to get very picky, some
edges may be too sharp. I don't know if they could be softened without too
much work.

I agree. Unfortunatly I'm waiting for a radiosity test. Now it seems that
it's going to be ready by next Thursday or Friday :-(
And those sharp edges... You're absolutely right about that, but I'm just
too lazy to get working on it at this moment. I think if I change the focal
blur to focus on the other side of the key I can kind of hide those sharp
edges, heheeheh

Even blurring the sharp edges might not hide them. Smooth edges just
reflect light differently. I keep on thinking there has to be a way to
use surface normals to simulate smooth edges, like maybe with the
proximity pattern or something.....

I prefer modelling the edges by hand using toruses, spheres and cylinders
instead of using a very slow isosurface. Unless I want to melt the key or
something like that...

With iso_csg library you are modelling using toruses, spheres and cylinders.
Since you have already isosurface in your scene you could at least try. If you
have no power for it send me copy of your script and I will translate and
render it with iso_csg.

There is a way to do this, I have already done it. I used an averaged
pigment of the object pattern of the object, each time a little bit
translated. It gives nice results for only a little bit smoothed edges and
is not too slow if you dont use too much samples.
