I wonder if anyone has actually tried to use the plugin. Usability horror.
The totem sidebar is like less than a quarter of the totem window, yet i have to navigate through a huge multilevel tree menu. (Nobody is going to copy with that). But it's a great project to try out though. :)
The web is a currently a better place for navigating huge amount of 'unknown' content. The current desktop apps aren't created for that purpose, it's mainly editing/viewing your own stuff. Rhythmbox/amarok and all the clones are the only apps that has a content navigation/browsing GUI. Totem doesn't - wrong fit ;).
iTunes isn't a music player, it's media-content-viewer where the content to be viewed is available in thousands. (But it still includes a web browser).
PS: I think this project highligts how hard it is to create something on linux and actually getting it out to 'real' users. They have to hook up with linux distributions who act like a huge gateway (stalling!) gateway for distributing software.
Sorry for the rant-offtopic post. Lwn is great for procrastinating :(.
