Which twitter client can synchronize unread tweets?

Question

Right now I'm forced to read all the tweets in a single client on a single device (TweetDeck on my Android phone).

If I would switch to another device and/or client, I would need to search for the last unread tweet, which is sometimes complicated (too many tweets).

So, the question:
Is there a client who can keep the status (read/unread) on tweets across multiple devices? My target systems would be now Android and MS Windows, but also Linux might be handy.

Solution

Had exactly the same problem and found http://tweetmarker.net/ very helpful. Basically you can choose from any clients listed on the site and it can even sync between different clients.

Now they have an Android client, but it looks like they've dropped the Firefox plugin.
