Add synchronization with a server
So, that the notes might be automatically synchronized with a wiki hosted somewhere on the Internet. Private vs. public flag would be required, and private notes would be visible only to the author.
I started implementing a DroidWikiSite server on Google App Engine. But will research TOmboy/Snowy as well.
Given the Tiddlywiki syntax being used, it would be really cool if it could sync to a server side Tiddlywiki application of some sort, likeTiddlyweb or Tiddlyspace. Both have a straight forward RESTful Api so it should be relatively easy.
Another option might be dropbox, via the official Dropbox app. Using a common Wiki syntax like Creole and a single file would be a good idea here: that way desktop apps elesewhere could sync with DroidWiki.
DroidWiki seems similar to Tomboy in certain aspects. How about syncing with Snowy so that the notes are available on the desktop too. Would also save having to develop a web service from scratch. See http://live.gnome.org/Snowy.
