If he/she sells just the .bip files, not the model geometries, then people who own Max and Character Studio and who also own Mike or Vicki could export their Vicki or Mike, load them into Max, load the .bip file, and just apply Physique without having to do any of the fitting of the biped to the mesh, adjusting falloff zones, etc, which is what takes most of the time in Character studio. With the biped already fitted, it would take less than a minute to make Vicki or Mike ready to use in Max with motion capture files etc. I have Max 2.5 and Character Studio... I don't know if that version is too old to be of use to you, but I volunteer to beta test if it isn't. -nemo
