I’m really wondering when we’ll see Twitter clients that can sync the read status between multiple systems and platforms.

I for myself often switch between my iPhone and my desktop reader.

On the iPhone I prefer Tweetdeck and Twitterfon. While on my desktop(s) I prefer (again) Tweetdeck and Seesmic. Originally I thought that Tweetdeck was implementing this desired functionality. But currently they only support sync for search queries.

Is this so complicated or am I missing something?
