Hi
It is EPSG’s
strategic intent to make the database web-enabled. A proof of concept
prototype is under
development at http://ocean.csl.co.uk/

there be one running instance somewhere in the internet that all udig

This is at yours choice.
If you want one running instance somewhere in the internet that all
udig instances hit, you can do the following:
- Setup a PostgreSQL (or some other) database on some uDig server.
For the following, I assume that a PostgreSQL server is running
on some distant server with SELECT permission grant for all uDig
users.
- Import the EPSG database in this PostgreSQL server (just run the
SQL scripts provided at http://www.epsg.org).
- Cut and paste the code in the box at the following javadoc page
(section "Any platform installation"). Put this code in whatever
class and package you want.
http://modules.geotools.org/main/apidocs/org/geotools/referencing/factory/epsg/package-summary.html
- Edit the server name, database name, maybe add a user name and
password. Bundle this class in yours uDig JAR (if dependency
to PostgreSQL JDBC driver is acceptable).
- Add a
META-INF/services/org.geotools.referencing.factory.epsg.DataSource
file (to be bundled in the uDig JAR). Declare in this file the
fully qualified name of the above-cited class.
Thats all. You can declare an arbitrary number of EPSG DataSources with
different priority numbers (for example a main server and mirrors used
as fallback).
