+# Cloud Apps
+
+Difficulty: easy to hard, depending on project choice and how far you want to push it
+
+There are a lot of applications that could potentially make good use of Tahoe-LAFS replacing the typical centralized storage of flat files or SQL databases. Currently supported projects include [TiddlyWiki](http://www.tiddlywiki.com/) (one of the Tahoe-LAFS developers hosts his blog using [TiddlyWiki stored in Tahoe-LAFS](http://allmydata.org/trac/tiddly_on_tahoe)), [Hadoop](http://hadoop.apache.org/), and [a number of others](RelatedProjects). 
+
+There are still many useful and interesting things that have yet to be built using Tahoe-LAFS. Perhaps the most promising is in the area of web applications; what applications can you think of that could make use of a highly reliable filesystem accessible from both desktops and [handheld devices](http://github.com/ctrlaltdel/TahoeLAFS-android)? Keep in mind that Tahoe-LAFS's architecture allows sharing and delegation opportunities that are difficult or impossible to implement using other backends. Some ideas people have suggested include a calender or photo album, or porting Mozilla's [Bespin](https://bespin.mozilla.com) editor).

+Nathan Wilcox wrote most of interactive tree browser frontend in JavaScript (see [the [RelatedProjects](RelatedProjects) page](RelatedProjects)); Toby Murray wrote [a front-end in Cajita](http://allmydata.org/pipermail/tahoe-dev/2010-March/004137.html); what interesting ways might this be extended?
+
+This is in some ways the most interesting area for development as it combines security and distributed systems problems with providing a user interface that lets a person who isn't particularly security minded operate safely by default. This is a hard problem, but offers great rewards in terms of learning, and even the ability to break new ground in safe-by-default interface design.
+
+Required skills: HTML and JavaScript for web applications. For other tie-ins, will depend on the base project (for instance porting the git DVCS to run on Tahoe would good C-fu, with git experience helpful).
