[xmlvm-users] Commercial usage

[Arno P. <ar...@pu...>]

Guys,

a while ago we had a longer discussion regarding commercial usage of 
XMLVM. We (the XMLVM core team) explained our dual licensing strategy, 
but we have not yet explained what constitutes a contribution for which 
we will grant the non-transferrable linking exception.

We had an internal discussion to clarify this point and we would like to 
solicit feedback from you.

XMLVM is released under the GPL license. If you use XMLVM to translate 
your application, the resulting source code will also be under the GPL 
license. If you would like to use XMLVM for a commercial product and do 
not want to release the source code of your application (as required by 
the GPL), we offer you a non-transferrable linking exception in return 
for a contribution to the XMLVM project. The linking exception will 
enable you to publish a commercial application build with XMLVM without 
having to release your own source code.

There are different ways to make a contribution to the XMLVM project for 
which we will grant you the non-transferrable linking exception. One 
option is to submit a substantial patch to increase the quality of 
XMLVM. Please ask us if you want to clarify whether your proposed patch 
qualifies as substantial.

Another option to make a contribution to XMLVM is by making a donation. 
We will grant the non-transferrable linking exception of the current 
version of XMLVM for US $300 per developer. The $300 donation will give 
the developer the right to use the current version of XMLVM without 
having to release the source code of his/her applications. This donation 
covers minor revisions (bug fixes). Major revision updates of XMLVM can 
be obtained by an additional US $100 per developer.

If XMLVM is lacking certain features that you need for your application, 
we also offer to implement those missing features on a contracting 
basis. Please contact us for details.
