I need a simple multisite Twitter feed plugin

I'm trying to get a twitter plugin to work on our multisite.

I've tried tweet blender as you suggest here:

but it simply doesn't seem to work, even with the latest version installed.

Can you recommend anything else?
It seems the new(ish) twitter API 1.1 causes a few problems. Ideally this is what I am looking for:

1. I add the twitter API keys etc via the network admin page. Regular users cannot be expected to know / create these
2. Joe Bloggs user goes to their wordpress site, activates the plug, and can add a widget to their sidebar that pulls latest tweets based on a @username.

Pretty simple I would have thought, but having a world of pain getting something that simple :slight_frown:
Suggestions welcome.
