yes, i had a look and it seems to be surprisingly simple to include its basic 
functionality (see below).

if i'm right, then KHotNewStuff2 is the thing to have a closer look at:
 o http://techbase.kde.org/Development/Tutorials/K_Hot_New_Stuff2

in theory, three steps are neccessary to get it to work:
 - ask newstuff.kde.org for a repository, see "GHNS repositories" at
    o http://newstuff.kde.org/development.php
   i'd volunteer for the repository administration stuff.

 - create a small rkward.knsrc file, e.g. with content like

   [KNewStuff2]
   ProvidersUrl=http://newstuff.kde.org/cgi-bin/hotstuff-provider?site=RKWard
   Uncompress=archive
   InstallPath=.rkward/plugins/

 - include KHotNewStuff2 invocation somewhere in the RKWard configuration 
   dialog. some code hints can be found at the end of
    o http://techbase.kde.org/Development/Tutorials/K_Hot_New_Stuff2

in the end this should open some "hot stuff" manager, show what's in the 
repository and allow you to download/remove available plugins. archives would 
get unpacked to $HOME/.rkward/plugins/. RKWard only has to make shure that new 
.pluginmap files are automatically added to its configuration. [btw, if it's 
not to big a deal to implement, i'd rather leave plugins packed in one archive 
file.]

as soon as this works, the .pluginmap window is probably the place that would 
profit the most from some changes. what i'd like to see there would be meta 
information on all plugins, which could be stored in the .pluginmap file, e.g.

Active  Plugin                             Version
  [x]   t-test                             0.5.4
        Two sample t-test dialog
  [ ]   ANOVA                              0.1b
        Support for ANOVA
  [x]   IRT                                0.5.4
        Item response theory (Rasch model)
  ...

i haven't found out about the details of the actually downloaded packages yet, 
but this is probably handled by the provider service anyway, so we wouldn't 
have to worry. can wait until we have something to toy around with, i think.
