[This idea is still under development, but comments are welcome on CaffinateDiscussion?.]

It's here now, just the core module, and not any documentation or examples. MailToRSS can serve as the mail example right now. More details are coming but I just wanted to get this out here.

Abstract

Lightweight component-based web application framework in Python

The component-based design of Toybox? in web apps has proven itself at my day job. However, Toybox? is work-for-hire proprietary tech belonging to my employer and will never grace the pages of this site. That's okay, though, because I may not need the full flexibility of the platform built there, and besides the Perl implementation is starting to show signs of strain.

The first immediate use of this project would be in the DesktopWebAppServer and any little web apps I write, such as MailToRSS, WeblogMulticaster, etc.
