One of the big issues of this application is to provide a quick generation and rendering of those treeviews inside normal browsers using javascript. The initial idea was to use a bare bone javascript xml parser on the client (jeremie.com like) to parse and create the in-memory data structure (DOMish) of thoses views, but that solution reveals not scaling when the user requests some 200/300 folders. The actual solution to those problems is to use a little hack on the server that generates directly html docs with the parsed js structure in as nested arrays and hashes that do _not_ need parsing anymore. The files with the "serialised" trees are a bit larger but the rendering performances are a _lot_ better. The code is still able to display textual xml treeviews. I think would be really useful to have a standard and more compact way to serialise (dump binary groves/structures) to some specific format (java, javascript,C,C++) or in a stream of "events" instead of pure text _only_. I am not saying that XML should be binary, but that the parsing businness sometimes is an issue. Just another brain dump.
