I have read your reference a litte more thoroughly now. It appears that the iframing page is calling a function in the iframed page only. However, there is *no* talking back to the iframing page! So, all your script does is use a url hash to trigger a function. This is no pretty much how paramifiers work in TiddlyWiki. Some background as to why WikiA can't talk back to WikiB in general: http://stackoverflow.com/a/1245166/777642 It appears that there is no way for iframed WikiA to push something to iframing WikiB, unless both are on the same domain. With a webserver, you could, perhaps, set up a simple proxy that serves pages external to your domain as if on your domain... thus possibly circumventing that restriction. If WikiA could thus actually "push" to WikiB, i.e. by WikiB implementing a timer so as to realize that the url in the iframe has changed, there could be some iframe (hidden via css only) serving the sole purpose of pushing stuff from WikiA to WikiB when loaded.
