SAP licenses NetWeaver to developers

I found this nice article which says that SAP netweaver can be now used by individuals:
http://www.regdeveloper.co.uk/2007/10/03/sap_netweaver_developer_license/

As I had experience working the the SAP netweaver J2EE Engine - AS (Application Server), I can tell you about my impressions.

The disadvantages are:

• It take a lot of time to startup the server and to deploy applications (depend on the application size)
• There are a lot of missing infrastructures which exists in other application servers (such as inline scheduler, cluster singleton, hot deployment) and many open source frameworks wouldn't work properly with the server.
• All the infrastructures in the server a propriety of SAP (Logging, Security etc')
• Except SDN there isn't huge community which can help with the development, Other J2EE Engines like JBoss has a lot of forums with questions and answers inside them.

The advantages are:

• There is a good administrator GUI to manage the server.
• It is possible to deploy several applications with references between them
• There is a good JCA, JCO, Web Services infrastructure to connect to the ABAP world.

Again this list are from my personal experience.
