During tonights EdTech Brainstorm we had some success sharing screenshots from Second Life using the free web-based conferenceing platform from Vyew.com. Thanks to Doug, JenW, Paul and company for the assistance. I was able to login to Second Life and share my desktop with the other folks in the Vyew session. They reported getting snapshots every couple of seconds. Perhaps this could be a solution for folks who want to participate in Second Life events but who can't get in-world for whatever reason.
