Status and availability of Nant tasks for Vault?

I spent some quality time today trying to get the source code 
from  vaultpub.sourcegear.com Nant Vault Tasks to compile and 
function today, and I seemed to not quite make it. 

I altered the using statements to reference Nant. instead of 
SourceForge.Nant and all the easy stuff.

I assume that code was written for a different release of Nant 
than I have been using due to the impressive list of errors
I received eventually when again trying to compile it. 

So does anybody have binaries of these tasks working with 0.85?
Do they work out fo the box with 0.84?

Is there a different place I ought to be looking than where
I am looking?

We cannot really convert to Vault if it does not have compatibility
with Nant and Draco. ( I believe I saw some support for Vault in Draco, 
but I haven't gotten that far in the evaluation process yet)

Any ideas, any help, anybody?
