Dynamic engine exhaust effects

[Bobe]

Are there any mods available or in the works that overhaul exhaust effects? What I'm referring to is the way the exhaust changes in appearance as velocity increases and pressure decreases.

This video is a good example of what I'm talking about:

Note how at about 1:20 the exhaust is a very fine column, at about 2:30 it's starting to expand out, at 3:00 it is much wider and has become somewhat transparent, at 3:50 the air is no longer burning red and we can just see a very wide vapour plume. At about 5:20 when the second stage ignites there is no visible exhaust (since there's no air to react with).

I'm not too learned on the subject of engine exhaust, I'm not even sure the terminology I used was correct, so if I have misunderstood something I'd be happy to learn more about it.

Anyway, I'd very much like to see these sorts of dynamic effects and I don't think it's the sort of realistic thing Squad has any intention of implementing.

HotRockets did have some expanding plum's http://forum.kerbalspaceprogram.com/threads/65754-HotRockets!-Particle-FX-Replacement-Tutorial but think the files for them was in the thread somewhere.

I'm pretty sure Real Effects did, i doubt if it still works though
