mmh, maybe a bit off-topic...

but it would be great if we could have, in this "animation container",
the ability to "animate" a property by connecting it to another
property, so that when the source changes the destination gets
updated.

This could have its own node editor view with nodes sockets
auto-generated from properties, where we could manipulate connections
and use operators like offset, clamp, sum, and all the way up to
constraints and custom python expressions.

I think something like make_connection(), break_connection() could fit
the Data API scope... but I guess it depends on how the animation
system will relate to it.
