Processing Twitter update

See the post about twitter.

We would like to put the XML inside the draw function, to get fresh tweets and do something with these tweets. The problem is the request rate: if you exceed the limit of 150 an hour (on a computer, called the client) you get an error:

<hash>
<request>/1/statuses/user_timeline.xml?user_id=111370675</request>
−
<error>
Rate limit exceeded. Clients may not make more than 150 requests per hour.
</error>
</hash>

So 2 times a minute should be possible?
Which means steering something around using tweets is too slow.
