Well GeoServer has a restful configuration api which allows one to upload certain types of files and have them configured on the fly. It supports shapefile, geotiff, and some other raster formats, no gml or kml at this point.
Also, no conversion to another format takes place. If you upload a shapefile it will get served from a shapefile.

We have thought about adding a scripting environment to geoserver, but this is really just an idea at this point. So the ability to "Script" geoserver via a language like jython, groovy, etc... The first steps (imo) would be to investigate and prototype how geoservers plays with jython. Would be run geoserver directly in jython? Would be embeed some jython scripts in geoserver, etc... > Thanks in advance for your thoughts and opinions.
