Mashup: Gmail and Twitter

I have to say that I still have mixed feelings about Twitter. On the one hand, I see it as a powerful tool harnessing the ideas of crowdsourcing. As a way to add email one-to-many and many-to-one functionality. On the other hand, I find it yet another fire hose of information coming at me at a time when I am not thoughtfully considering my other fire hoses. If it can become an asynchronous tool (not IM) to reach/leverage many people/thought leaders that is integrated into my personalized main knowledge tool of the time (Gmail), I am in! LINK

I see a few specific benefits of using Gmail as my Twitter client:

1) One tool for multiple modes of communication (email, IM, Tweets, voice-mail?, etc)
2) The ability to “thread” the tweets I follow (inherent to Gmail)
3) The ability to archive and search threaded tweets (some clients probably do this all ready???)

Can someone (Google? Other?) Make this happen, please.
