R help - Apr 2012 - multi-machine parallel setup?

Dear R experts:

could someone please point me to a page that explains how to set up
more than 1 machine for library parallel (which is quickly becoming my
favorite!)

my dream setup would be a design where I just pass a list of
hostnames:user:password to my parallel master, and then start R
listener processes on each of my slaves by hand.  R would start slave
processes automatically on each slave that has a a listener running.

I don't have the time/ability to set up full clustering
quasi-supercomputer solutions.

the vignette to the library(parallel) mentions snow repeatedly (esp
differences in its implementation in parallel from the original).
unfortunately, it doesn't give an example or tutorial for
multi-machine use with sockets.

could someone please point me to a simple working example, where a
master just has both itself and a 4-core slave on a second machine
(IP), and wants to execute an mclapply on a list on both machines,
like

   master.ip <- "localhost"
   slave.ip <- "Rfriend at 192.168.2.10"  ## has key ssh access
   mclapply( 1:100, function(x) { cat(x); Sys.sleep(1); x } )  # on both, please
