Ok so the new Vera skill works great!!! It definitely has slightly lower latency than my previous solution (HA-Bridge) and now I ca control my Nest's using Alexa via Vera too!
However I've found an issue, my Vera and Echo's are all configured to use Metric (you know the base 10 system that actually makes sense) .... but my Nest Temps show as Fahrenheit in the Alexa App. I can still issue temp changes in metric, without specifying Celsius, but it'd be nice if the set-point was in the correct format.
oh and I have a question, I excluded a couple of devices during initial Vera Control skill setup, how do I add them back in later on if I want to? NVM, I found the Manage Alexa options.
