I have sent a story to barrapunto.com (spanish slashdot) to spread the event by this local community (it isn't the same that it was years ago though). Let's see if they publish it.
Also, I'll try to move it by some spanish blogs related to Maemo and free software.

Related to the talks, I'm not an expert in any topic, but if it isn't possible to find a real expert, I could give the Python one or the Hildon/Gtk+ one.
It shouldn't be in the same time that the UX event though (if I'm accepted in the latter, of course).
