AAF may be the way to go once the XML version is available. XML must be text 
oriented (my proposal points to binary files but does not include them inside 
the XML itself). Once one can create such stuff, even without any SDK, the 
issue becomes moot.

Question is whether AAF is overkill or whether it is suited for ... linux 
audio? What I have in mind mirrors the way a program like Sonar stores its 
data (in its proprietary binary format) in a textual, open manner

Does Ardour already support (the binary) AAF? Does anything else we might be 
playing with? What type of XML stardard would opensource developers readily 
support in some form or another?
