The National University of Singapore is working on a plan to enable interoperability among networks of partner universities: The arrangement would mean that students on exchange programs could use the networks. But wouldn't they be able to anyway? I would think that a student from a university in Singapore who may be on exchange at Stanford would automatically be allowed to use the Stanford network. It seems that this plan has a broader reach, however, with plans to allow students from any of the partner universities to use any of the networks. That could be useful for traveling students who may not actually be exchange students. A similar initiative among European universities is underway, spearheaded by Portugal's universities.
