I'm about to start working with a remote writing buddy. We're going to send each other emails for 'clocking in' purposes, but we also want to use some kind of screen-sharing or remote login software to keep tabs on each other. Does anyone have any good recommendations for software along those lines? My netbook is sufficiently slow and old that if I'm not careful even typing can get pretty laggy, so resource- or processing-light software would definitely be preferred.
