I currently use Periscope in Snow Leopard but it's unsupported in Lion. I may be buying a new MBP in the coming weeks / months and in which case I'll need an alternative. I need something that will detect movement, take a picture and / or a movie and email it. What would be even better would be some sort of ability to set up streaming but opening ports in my firewall is all a bit mystifying / dodgy sounding. Thanks for any advice.
