asterisk users - Sep 2005 - CheckGroup accross multiple servers

I'm running multiple asterisk servers and need to use the CheckGroup
function (and other group functions) across multiple servers

Ex: 
- there are 5 channels in group test on server 1 
- there are 8 channels in group test on server 2
I would need a checkgroup to return me 13.

Any way to currently do this ?
What would be the best way to implement this if not ? Store group setting in
shared mysql?

Thanks
Ben
