I hope so. I try to always be open to the ideas and contributions of
others. As yet, however, Kai is the only other person operating in
this universe, and his goals and design space are pretty different
from mine. There's been lots of discussions of things that probably
*should* be a part of Ardour, but very little or no code. Thats OK
- I'll just keep waking up bleary-eyed but razzed with excitement.

Ardour really doesn't have to care about the EDL file format. Thats
the easy part (especially when people like timevista supply a
bison/flex parser for you :). The hard part is actually implementing
what the EDL describes. I have, oh, 80% of that in place, but as yet,
there is no way to specify gain curves or cross-fades. I know how to
do gain curves efficiently, but haven't found the time. the x-fades
are a lot more difficult, although i have some ideas.
I have the stuff from timevista, and I do plan to use it someday, but
its far from the most important part. Importing sessions from other
systems is a long way down the road, especially when those session
files are rarely come with a documented format.

I like to think of a bus as a point of data duplication. Before a
signal goes onto a bus, there is only one copy of it; after that,
there are (at least) 2.
