Well, today I found this warning:
Starting on April 2nd 2007, Support Package Stack for SAP NetWeaver 2004s will ONLY be available via SAP Solution Managers Maintenance Optimizer. Find more details here http://service.sap.com/solman-mopz.
This will affect those people like myself who run a small application server on their desktop to host something like the SAP NetWeaver Portal.
While as an SAP employee I can understand somewhat the reasoning for this, I also think it will make it a lot more difficult to get acceptance for the SAP NetWeaver environment in the wider community. A simple mechanism for applying patches to software is considered necessary by many, and hiding patches behind a more complicated environment will surely have a negative impact.
