Hello Mouaa!
I think I saw most of these being done so far, excuse me if my reply is a bit vague but I haven't done many attempts at custom shading lately. (no project far enough down development route for that yet.)
Here goes:
Quote: "1) Linear UV scroll texture based on time (i cna do it)"
I think we do have video - texture commands, at least rolfy has done this kind of work on his demon characters a while back. I had this kind of stuff up and running in FPSCreator a good 5 years ago. (in
Euthanasia and later on the displays in
Psishock)
We also have a bunch of skyscroll effects so I'd recommend sending a PM to rolfy and asking if he got any leads.
Quote: "2) In a model having some part with Self illumination and the other part as normal shader, do we need two materials ? or two sub objects ? "
You mean normal emissive mapping? The default shader supports that, you just need a _I texture (the emissive map)
Quote: "3) A shader displaying a material and blending it with a second diffuse texture (i can do it)"
Wouldn't that just be an overlay that can be done in an art program? (I'd need an example of this to help you further)
Quote: "4) Dissolve shader ? "
Ah! Like the Enemies in Doom3? Not currently, no.
Quote: "5) Night vision or Heat vision (i think i can do it) "
We had thermal vision in FPSCreator, so its just a matter of time until someone figures that out.
Here is nightvision:

Quote: "6) refraction shader for glass or torches heat ?"
Ertlov got refraction for glass working in his game "Fathers Island", just fire him a PM. As for torches emitting heat I'd take an educated guess and say: Not currently possible.
Did this help?
