Well, that will depend on whether I need it or not. If I can extract UDF 
files OK with the current libcdio, even if it requires an ugly 
workaround, I probably won't look that deep into it (time constraints).

I'd have to considerably ramp up my knowledge on those, as it is 
currently nil...

Have you had a look at what 7-zip source does 
(7z/CPP/7zip/Archive/Udf/)? It's a C++ Windows COM component, therefore 
heavily Windows oriented, but the license is LGPL v2.1 or later and you 
may find some information there.
