To make more than 10 web - callouts in same context

I have a requirement to search data immediately  from around 16 salesforce orgs. Since connecting and getting data from a single org needs  two callouts, i easily hit the callout limit. Could anyone suggest me a work-around..

@future wont help as I need the result immediately

Workarounds depend on attempted method of operation. Triggers have a hard limit, but you can bypass this through multiple namespaces.

 

Create three or four namespaces (different managed package orgs), and have them each query three or four orgs. When all are installed in the same org, they each operate in their own namespace govenor limits, and so won't hit the limit.

 

In Visualforce, you can script the callouts one after another using JS Remoting, Batch Apex, or just cleverly chaining together action/javascript methods.
