Sub-sidy/scription Business Model for ArXiv

Here's an alternative to voluntary institutional sub-sidy/scription model whose sustainablity is less founded on blind faith: Institutions have many self-interested reasons for wanting to host, archive, manage, monitor, measure and showcase their own research article outputs. The annual scale of their own local article output is also manageable and sustainable at the institutional level, within each institution's existing infrastructure. Hence what instead of trying to sustain a central repository like Arxiv -- most of whose costliness derives from the fact that it is a single direct locus of deposit and archiving from all institutions, worldwide -- direct deposit and hosting can instead be offloaded onto the distributed network of institutional repositories, with Arxiv becoming merely another central harvester, providing global search services (sustainable if it provides functionality that can compete with other OAI services or Google Scholar).
