Protecting source code

Hi,

I would like to ask if anyone knows of any reliable existing approaches for protecting ABAP source code?

As a supplier of 3rd party software, it is a concern that there is no protection over visibility, let alone maintenance of code (ie. READ/INSERT REPORT). This allows for intellectual property to be copied and server-based licensing mechanisms to be bypassed.

Alternatively, is anyone aware of moves by SAP to support this capability in the NetWeaver stack - given its hoped for wider audience in the development community?

I saw in a recent Business One presentation that it is not possible to access the source code, so perhaps the capability is already in NetWeaver, just not generally available?

Regards,

Scott
