If i find the one about the kevlar and knives, which is more likely what resistweave would be like, I will post it.

Here is a link to a journal article about it. One highlight from the article is that an army research study found that 4 layers of STF impregnated kevlar was as effective as 14 layer of untreated kevlar. So as far as how it moves, would not be too bad.

Ok, it seems that a 45% reduction in layers of material can be achieved when dipped in STF.
So if we take NIJ I for an AV of 6, that would be around 9 layers of Kevlar 29. If we reduce this by 45% that would be 4 layers. Now Kevlar 29 is about .61 mm thick when woven into a cloth. So that would be about 2.45 mm for 4 layers of Kevlar 29, too thick for a uniform, but we have other options to look at now.
Kevlar 159 (correctional fabric Kevlar) which is .18 mm thick when woven into a cloth and then Kevlar LT (comfort Kevlar) which is .15 mm thick when woven into a cloth

So looking at this information we could be using a combination of say 5 or 6 layers of Kevlar 159 and LT to come up with a uniform that is about 1.25 mm, which I think would be around the same as the current CORDURA NYCO fabric (need to research this more).
So I think we do have a technical solution to what Resistweave could be, but then this opens up the question of layered clothing, undershirt, shirt and jacket an AV of around 14
