You can use a Lightmap shader in xsi and then use the generated map to control a push operator. Then keep a little render region in the side of the viewport to update it in "realtime".  It is something similar,  but in xsi you must build it. An example to view procedural in a viewport : http://www.vol2nuit.fr/guillaume/articles/LightMap/LightMap.avi

To merge with Andre's mail, maybe I didn't expressed myself correctly,
but it's a blend of procedural modeling with textures - maybe I don't
have the right term for this.

Sitting 2 desks apart our lightwave guru, I see him modeling stuff with
procedurals that are really unbelievable, in real-time on the fly. It's
like real-time fine displacement. Start off with a 4X4 grid, add like
let's say 25 levels of subdivision - so 25 + on the num keypad in XSi -
and you're able to apply all kinds of procedural textures, and see your
*real?* geometry in the viewport instantly updating.

Sure the rendertree is really powerful, and I agree most of the
procedural nodes are still very basic since the beginning of XSi but I
think we'd still be missing something - maybe another bridge with mental
ray to get the resulting geometry in our viewport, actually seeing it in
wireframe.

It's as if we'd have fine displacement, updating in real time in shaded
view in one of the viewports.

It's very nice.
