I found it before my post. Unfortunatelly, this project is still in alpha (not production quality) and seems to be abandoned or freezed ... Coda is looking like a dead project, it is moving very slowly (unpredictable development on stable kernel-2.6 and probably few commits per year). Finally, i agree with you: lustre is the solution...
