Sarah at LibrarianInBlack points out that the new chat rooms launched by Meebo this week can in fact be used as a rudimentary shared browsing tool. I tried it and she's right - it's better than nothing.
What is nice is that it'll work when you're on Meebo and your patron's on a native client - they get a link to join the librarian-created room (password optional). When they click that link they'll be brought outside their client to a webpage containing the new Meebo room, and the chat will continue from there. Any URL that's typed in the chat session will immediately appear in a small window adjacent to the chat session so both (or all) participants can see the same tiny page. You can't interact with the page, but your patron can click on it to launch at their end and be on their way. Um, kinda like if you'd sent them the URL to click.
