As an alternative to Voronoi polygons, spatialSQL will solve this style of query.
 
Input polygons with some touching edges, buffered: www.spatialprojects.com.au\images\median2.jpg
 
 
Median lines on the function pad are free (2 selected objects)
As a general update, the registered version is required.

Hi folks

I am confronted with a bit of a problem and was wondering if anybody had
any clues as to how I might get around it...

The situation is this:

I have a table with complex polygons that I need to buffer - only I need
to maintain any existing boundaries between polygon objects - I can't
have any overlaps.

Is there a way to run a complex buffer that does not buffer any line
segment that is a boundary between existing polygons?

I had thought of copying my existing table, converting it to polylines
and somehow removing all lines that are unique, (theoretically leaving
me with only lines that are a boundary between 2 polygons) and using
this table as a "cookie cutter" on the standard buffer result, but that
will still leave me with loads of "slices" of polygons I will then need
to delete... and I'm pretty sure there are other problems with this idea
though that I don't even want to think about...

Any help would be much appreciated!

Cheers
