Upon further review I noticed some estimates that should probably be 
revised down:

6 months for the initial research is probably longer than necessary. Upon 
further thought I think 2 months is probably enough there, provided the 
next 4 months do include further research in response to feedback:

  - 2 months at 40h/week researching, reverse engineering and specifying
  - 4 months at 20h/week researching and responding to immediate feedback
  - 12 months at 5h/week responding to further feedback
  - 24 months at 1h/week responding to further feedback

The above estimate assumes significant further work on canvas. If the 
editor is able to say "no" to requests, which I think in this case is 
highly desireable, then I would probably revise the above to:

  - 6 months at 20h/week researching, reverse engineering, designing,
    specifying, and responding to feedback
  - 12 months at 10h/week responding to feedback
  - 24 months at 2h/week responding to further feedback


The other estimates seem about right.
