New function for Magento: get a Category tree's products collection

FUNCTION 1)

Suppose my website has the following category tree:

MAIN_CATEGORY_1

- sub_cat_1_1 (id = 1234)

- subsub_cat_1_1_1

- subsubsub_cat_1_1_1

- subsub_cat_1_1_2

- sub_cat_1_2

- sub_cat_1_3

MAIN_CATEGORY_2

- sub_cat_2_1

- subsub_cat_2_1_1

- sub_cat_2_2

well, what I need is a function (let's call it getSubcatTree(id) ) which once is called passing a certain category ID as a parameter, it returns the whole products collection belonging to that category's tree (with the given category as starting node)

Still considering the above example, I should call the function like this:

getSubcatTree(1234) ,

and it should returns me a products collection consisting of all the products located in any subcategory (and recursively on their sub-subcategories) down from the given node.

This means all the products located in :

- subsub_cat_1_1_1

- subsubsub_cat_1_1_1

- subsub_cat_1_1_2

FUNCTION 2)

A function - let's call it for example getManuCollection(collection) - which returns a collection of all the names of the brands of a given products collection (passed as a parameter).

In the end, I should use the getSubcatTree(id) to get a products collection and then pass this to the getManuCollection(collection) to retrieve the same products collection's brands.

Of course those collections should work exactly like a normal Magento products/attribute collection.
