[twitter-dev] limiting number of follower ids

[Allen]

I'm using this url to pull the id numbers for the followers of a user
(e.g., bob)

http://twitter.com/followers/ids/bob.xml

It turns out that if there are too many people who follow bob, the
return message will be an over capacity notice.  Is there a way to
limit the number of users, like you can do with other calls using
Count, or Since?

Thanks
