Hi Rudi,
AFAIK, GeoServer does not support queries like this. I would look
to PostGIS 2.0 for this-- a KNN solution has been written for that. I know
it's useable from a web services perspective by CartoDB through the SQL API.
CartoDB is released under the BSD, and also offered as a hosted service.
SpacialDB probably also supports this, as it's built on PostGIS as well,
although SpacialDB's source code is not yet released, so it's only available
as a hosted service at this time.
Best,
Steve

Subject: [Geoserver-users] find nearest features around point without
distance parameter
Hi,
Does geoserver support a spatial query like: "find N nearest features around
Point P" ?
N ... amount of maximum features allowed to delivered in result.
P ... coordinate from where to look for the nearest geoms.
I only found a way to query with a "buffer" or "within a distance", but
these are not desired as they need a metric parameter.
Mfg,
