Can someone write a program that integrates my gtalk status, facebook status, and twitter simultaneously?

I envision a little dialogue box that lives on my phone, laptop, and ipod. Whenever I feel the need to enlighten my public, I type into the box, and when I press "return," it broadcasts my tidbit to the world. When people want to know how I'm doing, they no longer need to triangulate between twitter, gtalk, and facebook, its all there just for them.

Upkeeping these things independently has become burdensome.
