[Dxspider-support] Controlling upstream spots

[Allen]

Hi all

Looking for advice as to controlling what spots are feed into the 
DXCluster network.

I have a site with multiple upstream feeds. I and others use the site as 
a feed for logging software and enjoy the spots.

I want to post spots to my cluster which are really only for local 
consumption, not all. So need to be able to allow some spots out but 
prevent others from going into the cluster system.

What would be the best way to approach this ?
Happy to research but currently lost for direction.

thanks,

Allen
