I may have missed a previous discussion on this, but will we be seeing a Windows testing build of Luxrender with the "noise aware/refine brush" feature soon ("pmc_test" branch), I wonder? And will we be able to use this with Reality-generated lxs files when it comes out? As far as I can see there were builds for Linux and Mac OS prior to the release of 1.1, but not for Win.

For anyone who doesn't know what I'm talking about, it's a feature that enables you to define an area of the render (with a brush tool) so that it will be given priority for sampling (e.g. shadows and areas with reflection noise). I don't think I need to explain how awesome a feature this will be.

See here, and note the linked forum discussions which tell you a lot more about it.
