IDEAlliance has posted the Call for Papers for XTECH 2006 taking place in Amsterdam, May 16-19. XTech is the primary European XML show every year. January 9 is the deadline for submissions. It's a nice show, but I probably won't go this year. Maybe 2007.
The W3C Multimodal Interaction Working Group has posted the last call working draft of the Delivery Context: Interfaces (DCI) Accessing Static and Dynamic Properties (formerly "Dynamic Properties Framework"). "This document defines platform and language neutral interfaces that provide Web applications access to a hierarchy of dynamic properties representing device capabilities, configurations, user preferences and environmental conditions."
