[melbourne-pug] OS license requirements

[Mike Dewhirst]

Apologies for cross-posting

I'm getting near to open sourcing a Django project and have to choose an 
appropriate license. Can anyone help me choose?

I have settled on the following requirements ...

1. Project source must be freely available for end users to view and 
download and modify and further distribute to others

2. But if user modified source is distributed the modified source must 
be freely available for others to view and download and modify and be 
subject to the identical license as the project source

3. However, if the user modified source is kept in-house and not further 
distributed the changed source may be kept private or offered back to 
the project as a patch at the whim of that user.

4. Project (and user modified) source may be combined with proprietary 
software but the project (or user mofified) source component remains 
subject to the same license. It cannot be distributed as a combined 
whole under any other license than the project license.

5. But it can be distributed as a combined whole with proprietary 
software provided the project (or user modified) source component is 
freely available for end users to view and download and further 
distribute to others under the project license even if the proprietary 
component is not.

BTW, Django doesn't require that my project use the Django license and 
of course I won't be distributing Django.

I'm leaning towards the LGPL but would appreciate feedback from anyone 
with contrary views.

Thanks

Mike
