RickE@valvesoftware.com at Valve Software will provide the Steam SDK once this NDA is signed.
I am developing a new film, to be playable as an instrument, with re-mixable assets. Central to the idea is the ability to perform and otherwise mod the film.
Q) Could it be possible to do a free trial of Steam in our R&D phase to explore its suitability for distributing our product?
[Rick Ellis] Once we have an NDA in place, I can give you the Steam SDK for you to explore.
Q) Do you have any planned support for Xbox/PS2 content management/distribution?
[Rick Ellis] No firm plans yet, but both are on the radar to be considered.
Q) What kind of business model do you have with external developers? A paid-for-up-front software bundle, a subscription service, relying on a percentage of sales?
[Rick Ellis] For a application distributed on Steam, our fee is 5% of the revenue, before costs. If you need us to host the software, there is an additional charge to cover bandwidth and server expenses.
Q) Do you have a standard agreement/package description for developers you could send me?
[Rick Ellis] Not at this time.
