[M4IF Technotes] FW: [M4IF Infolist] MPEG-4 and MHP and SMIL?

[Mandel, Bill]

(moved over)
This has been an interesting thread. Are we seeing a divergence of specs with similar user experience goals? I'd like to hear some comments comparing how user experiences/apps are developed in addition to how the various formats overlap. 
  Technology      Implementation/Authoring       Timeframe
     MHP             Java or (Bean Tool?)          Today?
    MPEG4           Scripting (BIFS Tool?)        <1 year
   SMIL2.0           Handcoding or Tool           Ongoing
    Flash              Authoring Tool             Ongoing
 DHTML/ActiveX          Handcoding?               Ongoing
Are there comparison(s) to be made between BIFS and SMIL? 
Regards,
Bill Mandel
