Yes, bring your own laptop... but please, as a backup and for documentation, make up PDF's/image slideshow so you don't get stuck with no way to present. There will be demo n8x0 ( I believe n810's ) for the projectors, no I don't know how they are connected, but they will be there.
Logistically I would also prepare slides/snapshots in case, for whatever reason, networks are slow or unreliable. We are packed to the gills and I would be very upset at having to rearrange/cancel slots at this point because you needed a 5mbps connection to complete your session. If you have special or unusual needs please bring it mine ( Eric Warnke ) or one of the other organizers as soon as possible so we can get things moving
