In the past, there has been raised discussion about adding a callback routine to be able to track file upload progress. The discussions has never really resultet in anything except for people agreeing that it would be a nice feature. They all started back in 2001 and as of yet, we still havn't seen any of these great features come to live.
I would once again encourage someone to take a look at Doru Pebrescu's excellent ideas at <http://pdoru.from.ro> http://pdoru.from.ro Other features that have been suggested are: - authenticate a user before accepting a download - stream the download through an encryption algorithm.
