more ideas for conference websites and webtech

Liming Zhu has lots of interesting ideas in An incomplete list of things a conference website can do.
Some ones I found particularly interesting:

• GeoURL enabled using a longtitude/latitude meta tag. Much easier to get your website integrated with all other location based services later.
• Google maps to conference/hotel locations. We also have a google earth placemark ready.
• Weather forcasting, weather history for the same period of the year.
• A Wikipedia entry for the conference
• Several pre-defined tags for people to share links (del.icio.us), pictures (flickr) and blog entries (technorati) regarding the conference.
• (Todo) A central conference wiki and blog system for participants to introduce themselves, upload vcard, write about the events and etc.
• (Todo) A central place for participants to upload their personal calendars or indicate directly that which presentations/social events/places they will attend so other people can catch up with him/her at the right time and place.

The posting also says I would appreciate if you put forward more interesting ideas.
