license

Hi Team,

I'm new to Drupal development and its legal issues related to GPL licensing, so, please read through my doubts/concerns and guide me in the best proper way possible.

We (as a team of Drupal developers) work for a service-providing company. Here, we utilize Drupal for few clients, using core and innumerable contrib modules.

Respected Sir, Madam
I have a C/C++ based application.

To configure this C/C++ application, start/stop this C/C++ application, I
needed a front end interface.

I have used Drupal, I have written a small module in Drupal to have forms and
all. Using that module I am able to manage front end requirement.

Now I am planning to sell my C/C++ application to some customers.
My questions are

1) Is it legal to use Drupal for front end interface of my c/c++ based
application.
2) Can I distribute Drupal code as part of installation package. I am fine to

Hello,
I've found default Drupal theme very clean and well designed.
My question is simple. Can I use parts of this Drupal theme with its css styles in other open source project licensed under GPL license?
Of course I will include links to drupal.org with information about used theme.
Thank you in advance,
Vanitas

Reading the news lately, there is a lot of legal battle over tech patents. For example, Apple and Samsung are fighting over patents to the point of stifling further innovation. In addition, so called "patent trolls" -firms who buy patents in order to make a profit from legal settlements in court- make matters worse.

How does Drupal's open source license protect against such lawsuits?

How strict is Drupal's GPLv2+ licensing policy? I've read numerous threads and reviewed lots of code, but it's still unclear.

Points of confusion:

• I see lots of code that's GPLv3-only or GPLv2-only in core and in contrib modules and themes. Yet http://drupal.org/licensing/faq/#q13 seems to indicate that such code is not in compliance.
• How is the MIT license interpreted by the Drupal-sphere in terms of compatibility and integration? I'm specifically wondering about versions of the MIT license that permit sublicensing.

This topic will be of interest to many people across various organizations today who are deliberating on whether to adopt drupal or not and if so to what extent.
