[Koha] Single OPAC for multiple Koha instances

Dear Friends, We successfully created multiple instances of Koha by following the link, http://kohageek.blogspot.in/2013/08/installing-multiple-instances-of-koha.ht... Is it possible to create a single OPAC for all mutiple instances? Our aim is to provide a single OPAC to users to retrieve resources from multiple Koha instances. Regards, -- Vimal Kumar V.
