Anyone make a titanium 1L wide-mouth water bottle yet?

I have been on the lookout for this for at least a year now. Everything I’ve found on the net thus far points to no one has been able to manufacture this yet, but everyone has it in the works to debut sometime this year. Apparently Thermos made one way back in the day, but it’s not sold in the U.S. anymore.

Q1: Does the Ti 1L wide-mouth (like Nalgenes) exist yet or not?
Q2: Is there some kind of limitation that makes this a manufacturing challenge, and if so, what is it? People have been making Ti pots and flasks for years so I can’t imagine what the challenge would be…
Q3: Does anyone know if Ti has to be coated or not to be food grade? Someone told me it did, but I can’t think of any reason to believe them. Seems to me Ti would be inert not unlike SS, and if you don’t have to coat stainless then you shouldn’t have to coat titanium. Further, my Ti pot does not appear to be coated….maybe if you were after some sort of superior insulation, but then there is “double-wall”...
