Another link from Sarah at LiB (this one via the lo-fi librarian): Yugma. I haven't tried it, but it looks to be a solid option if you're considering tools to share the desktop (co-browsing). The basic service is free and cross platform. It doesn't offer voice over IP, so you're stuck texting with whoever's on the other end, though they do offer a built-in audioconference option; for that you'd both be paying long distance charges to Minnesota(!). Might want to check it out if you're in need of such a tool.
