SLD for NW 7.31 PO with De-Central Adapters

What's best practice for setting up an SLD in a landscape with multiple de-central adapters? Our landscape:

• 3 tier landscape (DEV/QA/PROD with multiple QA environments) - java stack only
• QA and PROD will have multiple de-central adapters
• Each SID currently has a local SLD

My approach:

• Central adapter serves as central SLD
• Central adapter, via SLD bridge, sends data to de-central adapters and solution manager
  

The reason I'm choosing to create a bridge between the central and de-central's rather than have the de-central adapters use the central adapter as their SLD is to avoid having a single point of failure.

My question - is it possible to have the central adapter sync data to multiple SLD's? If so, how is this accomplished?

Thanks,
