Swift has a whiteboarding shared document editor based on OT from a GSoC student last year. It's not been submitted for XEPness yet - the start of work on that is visible at https://www.dropbox.com/s/fewo76yu3bnaoxv/xep-whiteboard.xml - it's high on Remko's list to work on getting this submitted. /K _______________________________________________ JDev mailing list Info: http://mail.jabber.org/mailman/listinfo/jdev Unsubscribe: [email protected] _______________________________________________
