It should be fully possible to sync it to external timecode (if one
write an alternative TimSource plugin object that hook up to the
timecode source). However, if a scene will play back in "real time" is
another issie ;) and it all depend on the compelxity of the scene and
using a computer suffecient for the task.

Everything that has a writable property in an plugin object ... hmm
guess, everything...

K-3D is a software for modeling and animating 3D scenes (like Maya,
Sofimage 3D, Lightwave...) and producing RIB output that can be rendered
by a RenderMan compatible render engine (Aqsis, Pixie, PRMan, 3delight
...)

However, much its functionality is implemented as plugins so we really
are render engine agnostic (you can use any render engine as long as
K-3D has a renderengine plugin for it that produce output), and can
implement pretty much any 3D feature we like (deformation bones and IK
is comming somewhere in the feature).

Currently, we have limited support for dynamic using the ODE library. I
guess there's nothing to stop us now to fully utilize it, we have only
draged out feets there and not written the plugins we should, yet. ;)

Since the milestone for 0.3/0.4 was complete engine/ui separation the
user interface for interactive editing hasn't catched up, and the
functionality we had was scrapped. But in the comming development of
0.5/0.6 our milestone is to implement a new fresh user interface (called
"next generation user interface" or "ngui" here on the list) with all
interactive editing in viewports restored.

Matt Zumwalt was working on 3d audio editing plugins for K-3D and a 3d
audio render engine for his MA dissertation. But I don't now the status
of the project.
