i've a scarse knowdledge about the web tools that we can use
i do not know what tools can i prefer to do this.
i've decided to use pywps, only beacouse whit it  i can use a grass  
sintax
to performs processes and use a lot of grass commands  that is  
familiar to me.

to produce wms map i'll use mapserv as it is, so no pywps for this,
what probably i need is to set-up a link into the kml that point to a  
form
where one can select what grass layer want convert to wms feature
use wps to export the layer (or produce it if no exist ... like ndvi  
etc..)
then use a script to produce a mapserv wms map to
  (at the moment i ignore how manage this part, never tried it)

and use pywps  to run specific grass script to produce some output
loadable with ossimplanet and put this output in a ftp connection
to download and load it.
