May we develop an Opensource .ECW, for example .OCW, with sources of

Yes, you should perhaps open a ticket (if not already done by someone else)
in OSGeo4W trac instance to ask for the gdal-ecw plugin to be regenerated

Yes, but the Epsilon lib won't read ECWs and you have probably to build GDAL
yourself against it because few packages will build it.
