Yes, we have used postgis and it is great, and a very viable alternative
to ESRI's ArcSDE product (which needs Oracle or DB2 from memory).
Likewise the geostatistical tools for R (there are several libraries)
look great, although we haven't used them much yet.
We did look at MapServer and were impressed, although it is even better
now. However, we though at the time (a year ago) that the amount of
effort required to set up MapServer with PostGIS was more than we could
manage at the time. But yes, we are keen to re-evaluate. We would be
even keener to collaborate with others who are working with Mapserver
and PostGIS. We are quite happy to run MapServer/PostGIS alongside
ArcIMS as a comparison.
