Is it just remotipart that's failing, or does the normal jquery-ujs remote request fail as well?
from remotipart.
Hmm good question, not sure. The initial errors I noticed in the console were:
Unsafe JavaScript attempt to access frame with URL...Domains, protocols and ports must match.
and
application.js:10244TypeError: 'undefined' is not an object (evaluating 'doc.documentElement')
However on another look, I noticed that the action of the form has a bunch of parameters added to it after hitting submit:
http://uploader-local.APP_DOMAIN.com/users/4e0a01311010dc0001000006/avatars/new?[object Object],[object Object],[object Object]&_=1325710055888
Which is causing a 404. My form looks like this:
simple_form_for(Avatar.new, url: new_user_avatar_url(@user, host: "uploader-local.APP_DOMAIN.com"), remote: true, html: {multipart: true}) do |f|

Hmm, I have no idea why your form has a bunch of stuff appended like that. That error with the iframe is a browser security feature. Probably look into what the correct way is to handle that, as I'm not too sure. A quick workaround off the top of my head would be to host the actual upload form on the uploader-local subdomain.
Other than that, I know I've seen gems which upload files directly to Amazon S3, and the way they usually work is by using flash, which provides access to bypass the cross-domain restrictions.
You also may be able to use the cross-domain.xml directive on the uploader server to allow for cross-domain access, but I'm not sure how that works with iframes.
EDIT: Rereading the error message, that usually happens when you are trying to manipulate the content of an iframe on a different domain from the parent window (which the iframe-transport script that remotipart uses does). Maybe search for this issue on the jquery iframe-transport project.

Ok thanks, I'll go ahead and close this and comment later if I end up solving it
