I've done extensive testing with: a local installation (default) www.ccmixter.org www.ccmixter.co.za www.esolpc.com/teacherhost www.opensourcecinema.org openclipart.org/cchost/ tvlivre.org/cchost
I've got problems with ccmixter.org, but I don't know exactly what's wrong. And with openclipart.org/cchost/, because ccPublisher raises a HTMLParseError, regarding a malformed start tag. But everything else is OK.
Yesterday I added upload and final pages to ccPublisher. After I change the way the files are read into memory and post, I will fix the upload progress bar. For now it's impossible to see the proportion of the file that was already sent.
Now it's possible to upload files to any ccHost Installation with ccPublisher. But I need to test it later.
After a lot of bug fixes, publishcchost works with all submission types. It returns upload failure reason, and search samples remixed by user too. I think it's cool. But now I need to stop working on it and start implementing these features in ccPublisher. A bad new: since Monday it's not working with ccmixter.org. I need to find the problem.
Now the interface of publishcchost is looking better. It displays labels form, not only input identifications. Although it doesn't display tips, it already get it from form
