There are already a few of these services that exist, and I use one of them.
Fremium Model:
- The service would be free, but limited to 1 torrent/day as free users (not clear about that).
- The downloaded files would expire in a short time frame, let's say 3 days, unless you pay an extra for storaging the file on the server.
Don't offer fremium, it'll be abused, a free 1 week trial would be a lot better that this. Secondly for 3 days is little less time I suppose, the service that I currently use support upto 30 days or more(not sure).
Thinking of an integration with Mega, after the server downloads the torrent, the file could be moved automatically to your mega account or something like that, the problems i'm facing is that I need the user credentials to do that (username and password).
Now that's a original idea. I have never seen a service offering that, I would very much like that but if you could integrate it to Google drive, that would be deal maker for me and switch to your service instantly.
