Ah, sorry, I missed that part of your post (or rather, I misunderstood).
Okay, pov doesn't support such a thing natively - but help (I think) is at hand.
Try Rune's Particle System include: http://runevision.com/3d/include/particles/

That would require flow simulation - you can do this with external
programs or in a very much simplified way inside POV, see for example:

Concerning your original post - i don't think Lightflow can do anything
like that.

Maybee mine english is not good enough but Lightflow can do this effect.
Right now I found some sample and rendering it (in Lightflow).
Thanks for reply

Well, in that case please show the example.

Now animation is near end: but it is not quite what I want :(
Yes it is "smoke like" animation but there is not object to intercept smoke
and made turbulence in smoke
I will you contac via e-mail if you dont mind!

Awww - you beat me by one minute. Now I've got to ritually disembowl myself
and everything.

That is html that explain exactly what I want!
And mine apologies to Mr Hormann : Lightflow cannot (at least I dont know
how) produce what I want.

This is a computational fluid dynamics simulation...to my knowledge,
nobody has done one with the ability to output to POV-Ray. Graphics
packages usually use particle systems for this sort of thing, which can
give convincing results, though not as accurate as this algorithm. There
are particle systems which include object interaction, your best bet is
to try one of those.

Are you sure the sample scene is making flow calculations to get the
effect or just faking the effect with clever placement of objects?

If you have some idea please tell me: in the other hand I will try to
produce this effect with huge number od particles.
