Jeremy,

I have identified some scenarios for embedded iframes, even  the innerwiki 
plugin, I will share, as suggested by you.

Please forgive me for my rampant imagination, these ideas come from real 
life challenges.

Given, a Parent wiki, even a single file wiki can spawn an innerwiki with a 
subset of tiddlers

   1. In the parent/outer wiki Accept some settings, Generate a seperate 
   wiki based on the settings, in which a user can enter their input and save 
   it to disk. Basically the parent wiki can be a TiddlyWiki factory. It can 
   generate multiple editions from the one edition and with access to the 
   resources / data of the parent, at least at creation time
      1. Spawn an inner wiki which is a standalone wiki containing the 
      results of a process designed in the parent wiki - in effect generating 
      report wikis perhaps for distribution into an intranet.
         1. The report wiki can be a light wiki, only with the results, not 
         the tools to generate the results and could allow for a chinese wall 
with 
         multi-client outputs.
         2. It could even include active plugins disabled in the parent 
         wiki.
      2. Generate a TiddlyWiki as a Document/Website (full or template) in 
      an innerwiki, giving it a unique filename, serial number and other 
features 
      (metadata Stored in the parent wiki as well) then save/export the 
document. 
      The parent wiki can hold a set of templates for the required tiddlywiki 
      documents, and the document can store reference to its parent. Thus every 
      wiki built is automatically known about by the parent "generating" wiki.
      3. Generate "forms" in smart wikis, and allow the answers (in Serial 
      number uniquified tiddlers) to be emailed in response (Ie the parent need 
      not be writable), and imported by the owner of the parent.
   2. Spawn an innerwiki identical to the outer wiki (all tiddlers), 
   install a plugin to the innerwiki and test it sandboxed, from the parent. 
   Optionally migrate changes back to the wiki or save it out and replace the 
   parent.
   3. Publish a parent wiki, that spawns innerwikis with generated tiddler 
   sets, or test data. Users can then replicate there "problems" and 
   "Challenges" in a defined wiki or data set, that that all users can also 
   generate. So if I am having trouble with a special toc, I can test it 
   inside a common wiki and share my broken tiddler and the named data set 
   others can replicate.

Questions arising

   1. Could we save and reopen an innerwiki injecting new content the 
   second time, or harvesting changes within the innerwiki when it was away 
   with another user?
   2. Could we allow innerwikis to be saved into the server hosting the 
   parent wiki?, node, AWS or php for example. 
      1. As a hosted Tiddlywiki solution
      2. The creator could then own the generated wiki but not the parent.
      3. Could we generate an innerwiki with access to an authentication 
   process, that allows the current browser session to be authenticated, then 
   exit that innerwiki and continue within the now authenticated parent?

With a view to continued innovation!

Regards
Tony
