Having had done film audio for a few months, I have to say it's a really difficult task for free software to handle as of the current state (Ardour + Xjadeo is not a solution).

Anyway, why not get together and provide THEM w/ content? The Blender team wants to test their capabilities, and in order for LA to do the same, I suggest taking the initiative first and offer something to someone instead of waiting for an offer. I'm thinking sound design collaboration:

* Create a team (open to all LA subscribers and anyone interested in Linux + Audio)

* Finalise registrants/team members (if you don't do this and decide to make the whole thing informal there'll be trouble later on)

* Set up a Wiki with the tasks; each member puts their name down if they want to undertake a task (eg. sound design for character so
and so, include a README of sort documenting the software used - can be a logbook if you want)

* Set up a VCS repo so each member can commit his work, and it can be reviewed and edited by others if required (perhaps a core committee; decided upon during the registration finalising stage) eg.:
