MapBox

Given that Mapnik and MapBox are intertwined being able to write to MapBox and style it, set zoom layers/extent, etc... itwould be extremely beneficial to have an FME writer. This would give the non web developer a MUCH greater ability to create on-the-fly, customizable web maps without knowing much in the way of coding. I envision it for times when a web map would be extremely beneficial for a consultant or client that wants a beautiful web map (i.e. via MapBox) without knowing CartoCSS or other web styling languages. Not that it's entirely an excuse but some people need disposable web maps that expire after n amount of time. I'm guilty of being creative in the solution via FME analysis but lacking in web programing but it would still be an amazing ability to produce a stylized web map for clients via FME and MapBox.

I don't think necessitating a link to MapBox should be required. The ability to write to MBTiles format would be very nice; but stand-alone, then the user can choose if they want to use MapBox or anything else.

I think that there are two distinct writers here one for 'raster' MBTiles https://github.com/mapbox/mbtiles-spec and one for MapBox Vector Tiles https://github.com/mapbox/vector-tile-spec/.
