We are building something like this at my startup. http://www.clikball.com http://www.clikball.com .. It is closed invite right now since we are still rapidly building it out, but if you want to try it out and see if it fits email me - anotherjesse@gmail.com We have private groups for sending to multiple people, sending to only to a single user. You can share publicly as well then anyone who follows you can see it (the twitter permissions model). We had the same wish :) Right now it is only usable via a Firefox 3 / Flock extension, but support for more browsers is coming.
