[erlang-questions] Open Source ErlSigtran

"Commercial" is an awful term to use when discussing software.

1) Open Source/Free Software explicitly requires that it is possible to sell the software product, so long as the source code is available, modifiable, and redistributable.  So, in that sense, it "allows commercial use."

2) However, many Free Software licenses don't allow a downstream developer to use the software in a traditional proprietary package (or any use that doesn't meet the requirements above).  So, in that sense, it "doesn't allow commercial use."

What I understand is that Anders wants #1, and Richard is saying he will offer #2.  They are not in conflict, if I am correct.

I hope this helps clarify things,
