Richard, You can do this with local files. This is exactly what I made for the prototype for twederation. I have not had any trouble opening a local wiki on a file:// uri and fetching things from another local wiki on another file uri.
If it is something that browsers are supposed to block it isn't happening for me at least. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
