Have you considered writing your model to a VRML file?  Then you can use a 
browser for your flythrough.  Frame rates aren't great and in my opinion 
the available VRML plugins have poor interfaces, but it might suit your 
needs.

Cheers.

Have you looked at http://www.monumental.com/rshorne/3dem.html, which is 
the
home page of the freeware 3DEM flyby animation? Don't know how you'd go
getting source, but you could talk to the Author.
Regards,
  Andrew Cooke.
