[twitter-dev] Lists Social Graph

[Unfair]

Getting user ids of all the members of a list is crucial for a feature
of my Twitter app, and paging through 20 ids at a time from each list
isn't feasible. (Most of the data would be extraneous, I just want the
ids.)  I see a suggestion was made back in Nov 09 to implement a
function like the social graph, which just gives ids - what is the
status on this feature?  Will we be seeing it in the near future?
