What are the advantages and disadvantages of the Liftweb combine over other HTTP push server technologies? - How scalable is the lifting combat operator? - design issues and dependencies, etc ..,

http://exploring.liftweb.net/master/index-11.html
I believe this is the only way to implement server push using Lift.
The advantage of using the Comet over Ajax survey is well described in the link above (reduced traffic / higher responsiveness).
