Doing JSON in web2py is not much more difficult. Here is example 11 from

def makejson(): ### this is a samle controller
     import gluon.contrib.simplejson as sj
     return sj.dumps(['foo', {'bar': ('baz', None, 1.0, 2)}])

Here is example 14 with ajax+wiki effects (complete code):

from gluon.contrib.markdown import WIKI
def ajaxwiki_onclick(): return WIKI(request.vars.text).xml()
def ajaxwiki():
     return dict(form=form,html=DIV(_id='html'))
