I think that's what you have to do. Shapefiles are not designed for
editing/deleting, but for fast retrieval. You could cache your edits
somehow so you only have to process the file once but I think you have
to produce a second (perhaps temporary) file...

Yes, it's an idea, but I was just hoping something more "clean" was 
existing...

Thx

the deleted shape to the new shapefile. Then replace the old file with
the new.
