Can access a remotely located ewiki database via PHP-RPC. Needs
a bit more setup (creating an interface and setting up passwords).
Could be used in conjunction with ext_multi to only have a few
pages located remotely.
prev << "db/zip"
next >> "db/ext_multi"

You cannot modify the README.plugins file, but anyhow any ideas or suggestion should as usually get filed on BugReports, UserSuggestions or even better the README.plugins.Discussion.
