Unfortunately, I 
couldn’t join the AGIT (“Symposium und Fachmesse für angewandte Geoinformatik“ http://www.agit.at) 2012 at Salzburg, but there’s a new portal for all of you (like me), who want to stay on focus in GIS topics.
Keep an eye on http://gispoint.de (powered by Medien- und Verlagspartner Wichmann Verlag). There is a sup-page gis.OPEN , where you find all papers & most of it on german of AGIT 2012. Great page with short abstracts and full PDF downloads.
