users creating data

[Stephen Lime]

Just to  clear things up. MapServer (the  CGI executable) can't write
shapefiles
and won't be able to do that. Too hard to do in  general fashion. However,
MapScript
CAN write shapefiles (with the help of XBase module). All  you'd really
need is an
applet capable of creating features and a MapScript program  could handle
the
output. MapServer or MapScript can certainly be used to  provide contex
(i.e. maps)
for use in digitizing. Note that there are lot's of potential  issues in
this (topology,
editing existing features, data QA, etc...).
