Upload files to drupal via web service (from flex/air client)

Hi All,

(Apologies for cross posting - I've put this at http://drupal.org/node/222404 before I realised this might be a better place for it.)

I'm looking for a way to upload fiiles to a drupal site via a web service (from a AIR/ flex application actually) and I after some digging, I don't see anything on the forums or in the contributed modules that addresses this, so I though I'd post before we go ahead and develop a module to do this.

The module would, very simply:
- allow basic management of files from an external client application (I'm working on an AIR application) to drupal via a web service.
- basically need upload, delete + something to list contents of a directory, simple creation date etc.
- not need to provide download as I'm not planning to restrict access to these files.

And my AIR (flex) client would allow drag and drop management of (certain) files on a drupal site from teh desktop (and would also be open source).

So my questions are

1. Does anything to provide this functionality exist already?
2. If not, are there any contributed modules I should check out and consider using/ supporting (webFM?)
3. would anyone be interested in using such a module & client?
4. Anyone interested in helping to develop such service module?

Thanks!
