The download page has the whole codebase in its entirety, GPL licensed: http://luminotes.com/download

The link to this page is at the bottom of the front page. It used to be more prominent, but I found people got confused about whether they had to download the software in order to just make a wiki.

You can browse the Mercurial repository online as well.

And as for your question about keeping the software in the "cloud".. The software actually does have some sharing/collaboration features. (Whether they're useful for your specific needs is another matter.)

I'd like to make a desktop version of Luminotes at some point, but I have no concrete plans for it now.

HUGE thanks! BTW, I've been experimenting with web-based software running on a desktop with XUL/WebKit-based clients that run their own in-process HTTP server (I've used CherryPy) and I like this approach: HTML-based UIs are way easier to create than typical UI widgets.

I'm using CherryPy, and I'd be very interested in hearing more about this. Feel free to send me an email.

I think the biggest hurdle in a Luminotes desktop port such as this would be replacing PostgreSQL with something like sqlite.

Another option would be to throw out the existing server entirely for the desktop version and use something like Google Gears.
