Enter the Open Komodo Dragon

I've always been struck by how little known the company ActiveState is, given that it's worked with many open source languages such as JavaScript, Perl, PHP, Python, Ruby and Tcl. Now it's opening up its multi-platform, multi-language IDE:

With the Open Komodo Project, the focus is on dynamic languages and the open web. Open Komodo is developed on top of many open source technologies including Mozilla, Python, and Scintilla. The primary development technologies used include XUL, JavaScript, Python, and C/C++. The Open Komodo platform will be entirely open source and licensed under the same terms as Firefox: Mozilla Public License (MPL), GNU General Public License (GPL), and GNU Lesser Public License (LGPL).

The Open Komodo Project aims to create a full-featured web development tool for client-side web development integrated with Firefox, Mozilla's free, open source web browser, and based on the award-winning Komodo IDE. This new tool, codenamed Komodo Snapdragon, will be developed in collaboration with the open source community.

Sounds good, particularly the integration with Firefox.
