Umm, just because a set-top box has GNU/Linux (or just a manufacturer's customized Linux kernel, and not much else) installed doesn't necessarily mean that it will be binary compatible with most Linux distributions; I'm fairly certain that such manufacturer's do that intentionally, so if Joost wanted to develop a set-top box version for a manufacturer's "Tivoized" product, it doesn't necessarily mean that the Joost set-top box is compatible with Ubuntu or some other more public Linux distribution. Same story goes for game consoles (most of which do not use public OSes anyway) and other appliances.

So Joost doesn't plan to port to Linux? Doesn't necessarily mean that Joost won't port to a locked-down set-top box in the future if that's what they still plan to do.

But still, nothing ventured by Joost to GNU/Linux users, nothing gained by Joost from GNU/Linux users. It would be a nice gesture for Joost to at least create an SDK for Linux devs or compatibility with Wine, but the FOSS fans, IMO, shouldn't feel like they're entitled to a Joost Linux port. It's only a gift (supported with ads, proprietary, closed-source), just like Linux (not supported with ads, non-proprietary, open source).

(I'm on WinXP, Haven't used it yet, primarily using Miro, too many XUL apps already.)

Rayne, porting an application from one Linux distro to another is considerably less complicated then completely adopting a new platform. I recently talked to the folks from Kontiki and they told me set-top box plans are exactly why they developed a Linux version of their player.
