Amazon S3 integration

Has anyone looked into integrating an S3 option in TinyMCE? I am looking at the Tantan wordpress plugin as an example and can get the php part of it. But the javascript/tinymce plugin part is beyond me. Below is my idea for it:

First phase
(1) use iframe/module to get tantan to work for MODx
(2) maybe use jquery ManagerManager to include the iframe in the manager content window

Second phase
(1) create a plugin button for TinyMCE to popup the working s3 editor (i would need help here. Have no idea of where to even start)

Third phase
(1) create a way where certain files are (defined by size, etc.) are also stored on local server (maybe less than 10MB). If s3 isn’t available, then MODx base_dir is local instead of s3.

What’s your thoughts on this?

IMHO, a better approach would be registering a stream wrapper for S3, then you could simply point the rb_base_dir to s3://bucketname/ and the rb_base_url to http://bucketname.s3.amazonaws.com/; theoretically anyway. Something like one of the following would be a good starting point:

Hey Jason,

That does seem like the easiest way. But then,
1. the client needs to upload the files via a seperate program to s3
2. tinymce still needs to be updated to get/put the the s3 files. because most clients will need to use tinymce for images.
