Emerson, I wish you success with your efforts. It has been quite a ride so
Just a heads up - from this link:
" The commercial license also gives you access to all of the features which
are not included in the open source version."
I personally find it a turn off and a red flag when projects do that. It
causes me to doubt their commitment to Free software. It does not always keep
me from the project, but if I am choosing between two, it can make a big
I invite others to comment as well for your benefit.
Also, since you are going down the dual licensing route, you need to develop a
plan for contributions. You are going to need for people to at least give you
some sort of writen license to their GPL contributions, otherwise, if you do
build any community of contributors, the GPL version will quickly outstrip
the commercial one which I would not mind, but which would defeat your
In light of the fact that if you start getting contributions, your income from
your non-free (commercial is not really the best choice of words here as you
can easily be commercial on the free side as well) licenses will start to be
based off of their work as well as your own, you might want to think about a
plan which would give some of that income back to your contributors according
to some published plan. I know of no other dual license projects which do
this now, but some may indeed be doing it without my knowledge. If not, you
could set a trend.
I see you are making your gpl code available for download at not cost. I think
this is wise, but just for your and everyone else's information who may not
know this yet, this is not a legal requirement. You could very well charge
per download or for the first download every month or whatever. Trying this
may greatly reduce your uptake, but it is legal.
Also, in our back and forth, I got the idea that perhaps you thought some of
your stuff might benefit from patents.
I thought you might be interested in what Don Lancaster writes on the subject:
I don't think I have read it all nor is it likely that I agree with it all,
but it is interesting.
all the best,
