Thats a cool idea.
Btw now that Picasa is the google+ picture service, did they lift the 1GB limit?
It's impossible for you to hit it if you upload your photos through Google+, as they'll always be resized to 2048px if they're over that limit. And photos 2048px or less don't count towards the 1 GB of storage.
You can upload larger images through Picasa and they won't be resized, but anything over 800px in Picasa counts towards the 1 GB. Videos longer than 15 minutes on both Google+ and Picasa also count towards the 1 GB limit.
I bought 20 GB of storage for Picasa earlier this year so obviously it's not a concern for me, even less so now.
