Brush mask data format.

Has anyone ever discovered anything about how brush masks are stored? Where and what. Are they bitmaps or vectors.

Take a look at photo:getDevelopSettings().PaintBasedCorrections:

Thanks John. I can see that's going to be an interesting thing to try and make use of.

Has anyone actually done anything with this, do you know?

See this post for a company that sells presets containing automatically generated masks: Re: How did they do this? Custom Presets

Hi John, what plugin are you using to perform this query?

The screenshot above was taken from the debugger in my Debugging Toolkit. If all you want to do is examine the low-level catalog fields and develop settings for a photo, you can use my free Show Catalog Metadata plugin, which is described in this thread: Can you save Local Adjustments such as brush strokes in Lightroom?
