I described how to do it. The code is not hard but I do not have time to do it. Any decent Java developer with basic JME proficiency shouldn’t have much trouble writing it.

The best overview written so far is the doc covering the transition from the old API to the new one:

It's not great but it's a start. I know someone was updating the tutorials but I don't know how far they got...
I completely spaced out on updating this, duh. OK , I now replaced the networking page with a solid up-to-date outline of SpiderMonkey networking. If I missed some details or was imprecise, tell me, I suck at networking. :)
@Paul, I moved your API transition page to:
