MapServer - ArcSDE feedback

[Piero Cavalieri]

Hi all,

the company for wich I work is taking into account to buy an ArcSDE license.
Is there someone which can give me some feedback (or links to) about
connection of MapServer with ArcSDE ?
I would like to know problems and advantages especially compared with
having data in PostGIS.

I think this could be usefull also for other people ...

Thanks
    Piero
