I'm uncertain about a few licensing questions. I develop a closed source application, that's communicating with an open source server. Are my assumptions correct?

Can I use an unmodified (L)GPL software on the server-side? I think yes
Can I use and modify (L)GPL software on the server-side? I think yes because I'm not distributing the server application
The client uses an communication library licensed under LGPL. Can I make changes to this library? Yes, as long as I provide the source of the library with the client software
Can I take only certain parts of an LGPL licensed software and make a new project? Yes if it's licensed under LGPL too.

I understand that linking to a program licensed under the GPL requires that you release the source of your program under the GPL as well, while the LGPL does not require this. The terminology of the (L)GPL is very clear about this. #include "gpl_program.h" means you'd have to license GPL, because… >>> More
