Frank Scholz is the hero again. The Coherence UPNP framework developer, after bravely fixing many bugs in Rhythmbox' UPNP plugin, added UPNP support to Totem.
Will get integrated in Totem itself in due time.
And after people whinged a lot in my previous post's comments, Carlo filed a lot of bugs, and while some of them are already fixed with newer kernels, others are getting fixed by our very own mjg59 (I know he doesn't like me being so possessive).
And as a proof that filing bugs helps other people, one user added himself to the CC: for all the opened EeePC bugs. Now he can monitor progress, help with testing, and disable his work-arounds when the time comes. Yiipee!
