Just a quick report - I managed to scrae together enough painted Tau for a 1500pt game the other day, so we tried them out. Unfortunately, we didn't have the GOOD camera, so no overhead shots this teim, but this should give you idea of the proceedings...

* and a Predator. Forgot about the Predator.
We played Capture and Control for three objectives, deployed in table quarters, with Chaos going first.
Nurgle deploy in a line as far forward as possible,
DP in reserve, spawn at the front and one squad of Plague Marines on an objective.
Tau deploy generally as far away as possible, apart from the closer Pathfinders and the Commander, who is hoping to close in on some vehicles in Turn 1. The opening shot of the game from the Nurgle Vindicators kills the Commander and all his retinue!
In revenge, the Tau gunline concentrate fire on the Vindicators and the Spawn, destroying one of the Vindicators with a first turn Railgun shot.
However, the advancing spawn are tougher and are only taken out when a Rapid Firing
FW squad are able to land near them.
Nurgle continue to advance as most of the lighter Tau weaponry fails to make an impression.
While the remarkably accurate Hammerhead pops open another Vindicator.
A dread advances on the Pathfinders while going CRAZZZY but fails to reach them, and is taken apart by lighter fire, helped by the five markerlights that get him first.
And the
DP finally turns up, immediately followed by the last Crisis team, who reduce him to 1 wound.
But this Crisis Team are immediately engaged by another CRAZZZY dread, who wipes out the whole squad! The Daemon Prince bounces out in the next turn to wreck a Devilfish before his last wound is taken by massed Pulse fire.
The final, untouched Rhino, deposits the other Plague Marine squad on a second objective.
And a third dread rampages towards the only Tau-held objective in the final stages of the game, pulling the Fire Warriors off of it and into combat. Remarkably, though, they hold.
And, while another Fire Warrior squad hold the Tau objective, both available Tau skimmers Tank Shock into the closest Nurgle objective, contesting it at the end of the game. One objective each - a draw!
"Wherever you tread, tread lightly. We are closer than you think and our blades are sharp"
