Steve, this is an interesting project and I hope I'm not too late to help you out. Came across your question quite by chance through Google...
I'm the co-founder of a service called HomeCamera. We're free (for now anyway), easy (no NAT etc), and you can use our "Auto-Record" feature to record images and/or video clips every 5 minutes onto our servers. You can share access to your camera (just hit "share" and enter the email addresses of the folks you want to share it with) and - here's a cool one - you can set up motion detection video recording to capture the chick hatching! (no guarantees though... lighting conditions can play havoc with this).
What we don't have is streaming video (though it's coming soon).
I hope you find the service useful. Let me know if there's anything I can do to help (write to support@ ).
