PPD (pay per download) program is questionable. Offering $40 for 1000 downloads, like wupload did, is ridiculous. You can see where it leads - wupload closed their affiliate program already.

Furthermore, other hosters offen pay for 'completed download'. It is technically tremendously difficult (if not impossible) to count complete downloads, due to the resume functionality, and due to download managers which download the file in separate pieces in paralel.

We are considering this option, however it is not clear how other file hosters can actually pay the big $$ for it without a huge financial loss, and how do they really count downloads. Paying for a visitor who actually downloaded something (regardless if complete or incomplete) seems more feasible.
