Are there any existing templates for backend-files to use the new http-request feature with php? (or anything else)

I am really happy to see that TW has finally adapted http-requests as a standard feature.
Am I completely wrong to suppose that it needs a backend to use this?
Would it be a good idea to furnish a standard template that allows to import - let us say - all files in a folder as tiddlers?
Is there any reusable backend template around?
