display pages from any cql-query in a page-tree?

[bolmstrand]

I would like to be able to display the pages from a cql-query in a page-tree. Is there a way to do that already? If not, what would it take to make it possible?

Many times our users need to get an overview of a subset of pages within a space containing a much larger set of pages. Cql seems very powerful and can produce very precise results when searching for the pages, but displaying them in a list doesn't provide a very good overview.

Ideally the input would be a root ancestor node and a cql-query. The pages from the input cql-query may not include all branches to the ancestor, but could be queried separately to return all pages needed to construct a fully "connected" tree to be displayed.

I need this also... (don't know why I can only answer, I'd rather comment...)
