Adobe offer trials of "Dreamweaver CS6". Whilst still allowing the user to get their hands dirty with 'code', it probably includes a number of functions to do neat HTML5/Canvas tricks.  I might also guess it loves using files from other Abobe products.

(I would be interested in what Ockham might find. Whilst not being obviously related to Poser; it would be pleasing to see what tools might help allow a Poser user to generate simple HTML5 versions of their Poser animations.)
