Yes looks like this is exactly what you would need. Please see
partialUpdate from CometActor. As an example you can see sites/example/
src/main/scala/net/liftweb/example/comet/Clock.scala. partialUPdate
function returns a JsCmd but there are of course implicit conversions
between JsExp and JsCmd.
What you're trying to do seems like an interesting thing for a Lift
demo app in the sense that it would provide an interesting visual
effect through CometActor.
