Flexible furniture layout

One space in our university project is meant to have a flexible (and frequently changing) furniture layout. For example, during the day there may be multiple groups of small tables and chairs to be used as meeting areas. In the evenings, the space may be rearranged to host a lecture. We are currently providing multiple switch lighting, with dimming options. Do we also need to somehow provide task lighting for those small meeting areas? We would have to install outlets in the floor, which would not be conducive to the flexible nature of the space, and tabletop task lights would use up a significant portion of the table surface, which may limit use of laptops, etc. Thanks!
