"Attached you'll find a proposal for using different protocols. The idea behind the new code is: 1.) plugins/apps register protocols which they can handle. This is done via osgDB::Registry::registerProtocol(aProtocolName). Plugins register supported protocols as usual via ReaderWriter::supportsProtocol(..), the Registry is updated accordingly. 2.) osgDB::containsServerAddress checks first for an appearance of "://" in the filename and then checks the protocol against the set of registered protocols via Registry::isProtocolRegistered(aProtocollName) 3.) the other getServer*-functions changed as well, there's even a getServerProtocol-function With these changes filenames/Urls get routed to loaded plugins even with different protocols than 'http'."
