<p>Hello Andreas</p>
<p>Thank you very much for your comment. These are definitely things
I did not think about.</p>
<p>Our people are in two separate buildings (in two separate
regions!) but our systems can handle this without problems.</p>
<p>The editing conflicts seem more serious to me. I guess these
could be minimized by encouraging users to save edits more often
but, as you write, a proper solution may require proper
versioning. But then that may likely push up the costs.</p>
<p>Good material for thought and a test.</p>
<p>Thank you again!</p>
<p>Hernán</p>

<p>In my experience, using Postgis sources over the internet (not
in the LAN) is way too slow. It will only upset your users. In
such a scenario you would have to set up replication.</p>
<p>Another aspect: avoid editing the same features simultaneously
by different users. Only the last save will stay. QGIS starts an
edit session and will only save at the end of the sesssion, when
you actually save the features. In such a scenario you should
assign certain geographic areas to different users (e.g. user A
edits features in municipality x, and user b in municipality y,
but not x).</p>
<p>Otherwise you will have to deal with handling conflicts. That
would require more complicated table setups with versioning and
conflict detection.</p>
