1. SUMOVER Project workshop: 28-30 November 2005, UCL. Top new features list – ordered (1 st pass) Set up decent CMS (e.g. Trac) - feature requests/voting, –bug tracking & dev by others – main rep at sites. –Visibility: AGportal, AG-TECH, Freahmeat, srcforge –Put up this list – Working items –HW support input –Make clear of unstable RAT stability – error reporting – useful/automatic bug –Multithreaded mode –Mbus fixed – without mcast –Padlock security icon VIC – receivers listed in main window –Padlock security icon Startup GUI – address, keys, codecs? GUI simplification Clean compilation Multi-OS support –AG – less importance on OSX New codecs H.264 (external contribution) Full screen video/arbitrary video resizing (external contribution) Smart tiling – work from Taiwan –All video in one Thumbnail sorting Desktop sharing (compatible with inSORS?) –inSORS: H.264 “Data mode?” –VRVS: H.263 baseline Video subtitling/watermarking (like the news!) (Release) Who's speaking functionality (external contribution) Firewall/NAT traversal (UMTP?) –Port number in use P2P (e.g. aspen) – source specfic behaviours (external contribution) SRTP support –Signalling issues, rekeying H.263 improved (UKERNA) – dependent upon GW initiative Low bandwidth support (i.e. don't receive video if don't want) (Release)

3. SUMOVER Project workshop: 28-30 November 2005, UCL. Security Secure RTP – stream security? - Would be nice but not essential –Used a lot – AVT –Re-keying necessary, control channel req’d –AGSC bookings – Manchester Venue Not any other stable UK Venue Servers Security assumed –Needs to be non-obstructive Key distribution –VRVS future key dist for Evo Session Description security –AG: Globus based (will change) –VRVS – username/Passwd, Plugable Auth, Use tunnelling system (non-std) - Streams not encrypted User level notification –Padlock icon Firewall friendly –Probably Tool independent –ICE methododology –VIC: port usage Use Common lib? –Handled by AG2.4 for WinFW
