Display only the brands that is in the category

I'm setting up a shop and have managed to set it up so it displays related products directly underneath the product currently under display.
I would also like to display the chosen categorys brands above the products if that would be possible? Can't find a way to do it, have tried to copy the module with the related settings but when changing to brands it always displays all available brands instead of only the ones in that particular category.

Any pointers?

Could it possibly be something for a future release?
I'm sure it would be greatly appreciated.

Anyways, thank you for your time answering me.

Ok
The way I would LIKE it to be set up is as a filter that shows only the brands of the particular category that I'm watching. Clicking on a brand would result in the showing of only the articles of that particular brand in that category.

So it's not on the product page itself.

For example:
I'm selling harddrives. In the subcategory 3.5 inch SATA I could have four different brands listed. As it is now it's hard to easily see the brand of a disk, especially if there is several pages of them. Above the listing of the disks there would be a listing of brands, clicking on lets say Western Digital would result in the shop only displaying the disks in that category made by WD.
