Joomla 1.5.8 corp site needs to integrate a content delivery network-this is amazon's cloudfront and S3. Client has to upload and download files up to a 100MB each. The limitations of the PHP settings on the server keep this from happening.
I am open to your ideas on how to get this done. I was thinking a plugin with access keys etc might work with docman or some other doc management tool for joomla. Let's discuss.
