So, once again I don't use any GPL code. I can write my own PHP wrapper which will provide the same API functions like WordPress, e.g. set_option(), get_option() etc. In this case my code will never be a GPL product only because its functionality and API function names are similar to WorPress.

P.S. Actually I did that already. When I sold my xPinner plugin for WordPress, the potential customer said that they don't use WordPress and want my plugin as a stand-alone product. Since it was not a good idea to rewrite the whole plugin and lose an access to updates etc, I sold it to them "AS IS" but made my own PHP script which implemented WordPress API function names. So my WordPress plugin was working on customer's servers without WordPress itself. Just like Microsoft notepad.exe works on Linux without Windows...

P.P.S. There is no problem for me to say that my code is GPL actually. It won't change anything, because my code is not encoded, but it has a licensing system and just won't work without permission of cyberseo.net server which it is fully integrated with. I mean it's can't be pirated. In other words, I could use any open source code and fully comply with GPL, because that code would be used as a service. As an example, my code is compatible with GPL Full-Text-RSS script, which is not included into the CyberSEO Pro package and should be downloaded/installed separately and used as a service via its API. Just like Google Translate API, WordAi API, ArticleForge API, YouTube API, PornHub API or any other 3rd-party service.
