Comment Service and Flex : how to get all comments in one call

Hi,

I am on my way to build up a flex app to manage comments moderation for drupal websites that handle a lot of them. I noticed that last dev version of Services offers a Comment Service which is really useful. The thing is that it seems impossible to get all comments from website (only those linked to a given nid). I am not a WebService expert (far from it) so maybe I am missing something.

So I am about to code something on the flex side to iterate through all nodes with comments (which is surely not elegant way of doing at all) except if someone can light my way here. I was also thinking to use a module (can't remember the name) that use node as comment. Might do the job but it's not a drupal native solution...

Cheers,
Matthieu
