How to output posts from specific subdomain sites?

Hey all,

I’ve pored over the various widgets and plugins for collecting and displaying posts from all the sites on a WPMU install. What I’ve not been able to find as yet is the ability to have more granular control over display.

For instance, it would be great to be able to have a widget that offers me the choice of which subdomain (or directory) site to display recent posts from. Having the option to add category display control on top of that would be total gravy, but not going to get greedy!

Any suggestions? I’ve done some extensive searches and just not seeing anything pre-made out there. I’m sure it exists, but it’s not finding its way to me.

Your help and suggestions would be greatly appreciated!
