I was thinking to use lift-json in this case ... but I'd also of
prefer having a lift-js project.

Depends what you mean by unify. lift-json is not the same with js
support, js should utilize lift-json to build json constructs being
part of the javascript generated but lift-json has nothing to to with
a potential lift-js project. Therefore I would keep lift-json and lift-
js separated and have lift-js utilize lift-json whenever possible.

Too soon to tell. I'm not sure yet if people like this proposal so we
first need acceptance and then talk schedules.
