At first I need to say that coWiki didn't require JavaScript so far. If you
want to change this basically, make it good. Means: if you want to use JS
someday and take it for granted for coWiki to work, you may replace some
functionalities with JS directly. These may be e.g. already existing
dialogues.

Such (XML)-RPCs/requests like this AJAX (horrible name for an old
technology) provides, make sense in at least two coWiki cases:

 a) The display of the tree if you want to move documents. To select the
    target branch you may use XML-RPC to retrieve the subtree data to be
    displayed. This would also scale in the case that the tree has > 10.000
    nodes or such.

 b) If you have a smart textarea that displays an additionaly layer with
    document name suggestions after you typed "((" or "[[" and a few
    characters. I think I don't need to describe this functionality further.
