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
against GDAL 1.9

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.
