I see room for improvement here ;-)

@Marc Unger, can you please read the docs provided in this mail and
update / rewrite https://wiki.horde.org/Doc/Dev/HordeAjaxApplications so
that it is straightforward usable as a tutorial? You can break out into
a sub page if it gets too lengthy.
  

See https://github.com/ralflang/horde-boneyard or
https://github.com/horde/ansel/blob/master/lib/Ajax/Application/Handler.php
for a demo or

https://wiki.horde.org/Doc/Dev/HordeAjaxApplications
https://wiki.horde.org/Doc/Dev/HordeAjaxApplications/Example

for instructions

You basically issue HordeCore.doAction(action, params, opts) in js, this
in turn (via steps omitted here)
calls $App_Ajax_Application in $App/Ajax/Application.php
See example
https://github.com/horde/ansel/blob/master/lib/Ajax/Application.php

The _init function basically loads one or more handler classes which
provide actions
I never really grasped the "Imple" concept, you most likely won't need
it for new code.

A Handler extends Horde_Core_Ajax_Application_Handler and is a
collection of methods which have no parameters and return either a
string (html) or a Horde_Core_Ajax_Response object or an array structure
which gets turned to a json
