Well it's not easy to add this to http since HTTP stack could be
consuming but you could imagine some sort of magic URI handled quickly
by remote Tomcat (at the connector http/ajp side), and have some sort
of timeout associated to this request.

For the load-balancing algorythm, do you plan to propose a bunch of
pre build algos and let users select the right one for their use or
allow externals modules ? We could see that like mod_jk / mod_proxy
modules like apache modules  does for HTTP...
