I’m not sure if this is new or not but you can pull a live feed from Vatican TV online now. The feed, via the Vatican website, is provided in RealMedia and Windows Media Player formats in three bitrates.
On a related note, the Papal Funeral Mass will be presented live at St. Mary’s Cathedral in Austin. Everyone is invited to watch it, starting at 3 a.m. Friday morning. Following that, Bishop Aymond and various priest-concelebrants will celebrate Mass. Lastly, a light breakfast will be provided.
