[Koha-devel] Federated OPAC for Koha

Hello All, We have deployed Koha 3.0.2 in our university and few others universities are also using Koha in Pakistan. All those willing to collaborate with each other through some unified OPAC so that patron of one University can access catalog of all Universities in collaboration. Is it possible in Koha? Any guideline in this regard will be highly appreciated.
