Single GF entry on several sites

I want to use GF to enable visitors to send in text and image(s) that will be placed as a post on a wp site. (examples of how a customer has used a special paint that can inspire other website visitors)

With GF this is easy for one site. But is there a way that these entries are posted on more than one WP site.
So when an entry has been send through a form on site A can it be posted on site A, B and C?
And not by posting it on every site manually but through the functionality of GF.

Is this possible to accomplish with GF or is this something outside the scope of GF and should this be done with Wordpress itself.

Suggestions are welcome

Thanks for the answer.

I am not sure I understand your idea. This way the form itself can be displayed on Site A, B and C. What I want is to display the posts on site A, B and C.

What I thought of is to create a subdirectory, place the index.php in it and call the wp-blog-header.php from the directory that contains wordpress files. Then make a file that contains the loop and displays the posts. Then call that file with php include into the site B and C etc...
I am not sure that this is the best way but it should work.

The feature you suggest could be interesting. Not something I have thought of but I can see it put to use
This is a Wordpress 3.0 install, but without the Multi Site setup.

I agree with Carl. You could do this with the very powerful FeedWordPress plugin. You could take the posts feed from Site A (suggest you use a category feed from Site A) and, with FeedWordPress installed and configured on Sites B and C, you could populate those sites with the catagory posts from Site A. FeedWordPress enables you to parse the incoming feed items as posts and you can set it up to automatically check the incoming feed and allocate the feed items to specific categories. Very powerful. I've used it on a few sites and it works very well.
