I agree. I will change ardour to store the files as one of the above
formats. Its a trivial change, I think, since ardour's file are
preallocated, and so the header information never (well, very, very
rarely) changes.

yes, i think this is a good approach.

well, it depends on whether you're using an audio sequencer or not.
the model i am working with is this:
* incoming analog audio goes to a A/D box, then through a digital
mixing console and onto a multitrack digital recorder
* gradual buildup of tracks done on the recorder until we
have good takes of each track
* switch out of mixing console mode, and go to computer (mouse,
keyboard) to run an editor (move, cut, splice,
crossfade, etc. probably no mixing though)
* run resulting edits from the recorder back through mixing console
maybe my model is wrong. perhaps an audio sequencer is needed.
I don't think you can really do per-track editing. the edits to each
track have to happen in the context of the other tracks. an example
from yesterday: my friend's percussion ensemble Spoken Hand were doing
a session in a ProTools studio, and we did several edits that involved
moving individual drum hits by a msec or ten. There would be no way to
do this correctly one track at a time. Is this editing a track, or is
this messing with an audio sequencer ? thats a difficult question. i
would rather avoid the protools all-in-one approach.
my big concern is the use of an editlist, which is vital for large
files. programs that expect to be able to rewrite everything they do,
even at the end of an edit session, are not going to be useful. we've
*got* to consider the raw .wav/.aiff files as "immutable".
