ok, I've setup a separate maemo project for the gui component, which I've named Squishee: http://garage.maemo.org/projects/squishee/ you can grab a file release there.

Squishee doesn't do a great deal at the moment (decompression only), but the hard work has been done (getting all the desktop icons and dbus stuff working correctly) and I'll add features over the coming weeks.

Technically the file release is an OS2007 package, but as it is pure python, I think it should also work on OS2008 (unless there are changes to how the desktop files are deployed). However, for it to do anything useful on either platform you need to have the 7za command line tool installed (I'll support other tools in later versions).

For OS2007 you have two options: grab my deb linked in my first post, or go get the p7zip package from the maemo garage: http://garage.maemo.org/projects/p7zip/

I'll make an OS2008 package of 7zip when I have time.

If you get time to test leave feedback here or use the bug report/feature request mechanisms on the project page. Source is available in the SCM repository (but needs a tidy up)
