The last part of the paragraph "exchanging complex internal data

But if you can demonstrate that the pipe/socket/command-line communication is generic and allows, or would allow, your program to work with other, non-GPL programs using the same protocol, you're fine.

Shipping a commercial POP3 / SMTP server along with a GPL email client for your customers to use (or vice versa) would fit because POP3 and SMTP are generic protocols implemented by a wide range of software.

It has been made clear on this list though that MySQL considers their protocol unique enough to protect.

In Germany, like in whole europe, and probably other countries too, it is very hard to protect concepts. While concepts manifested in code, CDs or such might get protected, pure ideas and concepts are totally different (except music). _______________________________________________
