I'm beginning preliminary work on the bringing the digital downloads to core. Right now I'm trying to build a list of most needed features and how to implement them. I'm also going over cPill's implementation to see how his solution works. As far as time, I've never been good at estimating time to complete coding projects. It took me a week to hammer out the uc_roles module, but I know this module is going to be more work than uc_roles. How about we say the release is..."when its finished"

I would also like to hear other people's thoughts on what is needed for a file download product feature.
