I think major technologies of 2008 are going to be telepresence and unified communnications.
Telepresence would use conferencing, 3d Net , or Mobile or other gadgets to make you interact with others in the real time. People will be able to talk to vendors around the globe in real time. MICE costs would be reduced by means of Telepresence.
UC will also make it possible to present a single identity of the user to the interacting public through a common ID to reach them by e-Mial, or Cell, or Land Line et al.
