Hi Socratis,

my preference would be keeping this as low key (and limited audience) as 
possible until we have more accurate planning data - currently there 
isn't a line of new code in the tree (i.e. we've not reached the "proof 
of concept" or "prototype" stages), and it's totally unknown how long 
it'll take to get the code working. Even if I don't make the most 
pessimistic assumptions this could take until 2018 to go beyond the 
break-even point compared to the existing 3D code. Don't want to create 
false hope at this early stage which leads to more frustration.

We're still doing small improvements to the existing 3D code if there's 
genuine customer need, but that's exclusively bug fixing, not adding any 
new features.
