The good news is that Greenhouse will employ InstantAction's streaming technology on its site, allowing you immediate access to selections from its catalog. "Indie devs think the same way we think about it," Penny-Arcade's Robert Khoo told Big Download, "which is that since they have the option to embed the games into pretty much anywhere, it's a win-win for everyone involved."
The bad news is that you'll have to ... wait for that immediate access. The Greenhouse site is currently down while the new InstantAction stuff is being implemented. Khoo said that it would be back up before PAX, which starts September 3.
