I've created wiki page:

http://wiki.maemo.org/Open_Media_Player

It's far from being perfect, I think I'm not best person to fill lacking info now, as I'm (yet) not user of OMP I'm sure gidzzz will fill info about features - everyone else, please correct possible mistakes, provide links from used terms (that already got wiki articles) etc.

If someone is too lazy... ekhm, occupied to edit her/him-self, You can always send me or gidzzz info about mistakes in PM.
