javascript - CherryPy Real-Time Web Application -

i've inherited web application running cherrypy web server. need implement user interface automatically update data server. right solution use javascript polling. while works, feels dirty.

i love use socket.io, cannot find support doing cherrypy backend. 1 have insight approach?

websockets great too, except need support ie. there non-flash fallbacks ie? , websocket support in cherrypy have found ws4py, don't know have experience using it.

are there comet implementations cherrypy.

for it's worth have been scouring internet last few days looking solutions, haven't found "this can do" results.

is possible , make sense install node.js , have client ui communicate node.js server talks cherrypy? or wasteful?

thanks!
