If all the threads about glass-water dilemma are too long to read through, in short:

It would be great if we could tell Maxwell a distance limit, and two poly faces within that limit should be considered as lying one on top of the other, with no space, or "air" between them.

I second!
Yeah, I want this till 9th of March
And no doubt it was the first time this TOLERANCE idea comes around.

Yes, I know, but mine has a better name

[tom]

tolerance yes yes... tolarance no no tolerance... hmmm tolarance...

[Mihai]

no no.....it's "Ray Distance Tolerance", or lets please the acronym freaks and say RDT.

Btw, I already patented it.

[tom]

you selfish! ..heheh
no i patented it first... it's TTT ... Tom's Tolerance Trick

[Aldaryn]

I second this wish.

Isnt its hard to say TTT? 3T maybe?

I second this too, but it would be great if we have also correct handling of refraction through coplanar polygons.
Sorry to post such an ugly pic, but :

this is how coplanar dielectric polygons (normals facing oposite ways) render now. Liquid inside is suposed to be wine.

wow a magic render!

I second this too, but it would be great if we have also correct handling of refraction through coplanar polygons.

If youve got a TTT, it'll deal with this coplanar issue automatically also. Coplanar polygons are always within any threshold.

Regarding the coplanar surfaces: This would be handled by the RDT as well. Unfortunately I don't know of a single implementation of RDT in any software renderer, which points to a problem that's hard to solve. Coplanar surfaces are quite bad anyway...

IMO it would be perfectly sufficient to supports NDs lower 1, because then a liquid overlapping the glas renders just fine.
