Re: [xmlvm-users] Using xmlvm in a commercial product

[Kevin G. <ke...@co...>]

That's a real shame, it essentially limits your user base substantially
since the majority of users are likely to be wanting to port existing
android applications to iphone.

Couple of questions around this:

1) The tool itself is GPL, but does that license cover the output? GCC for
instance might be GPL but that doesn't make the object code it produces
GPL.

2) Presumably the objective C compatibility library is also licensed under
GPL. Is there any chance you'd consider licensing just that part under a
more permissive license. This way no one could resell XMLVM but the output
would be usable in a commercial sense.

3) If a user were to develop a new compatibility library (say me) and use
this instead of the existing GPL one, would you consider that library
linked with the output of the tool to be free of GPL?

Unfortunately it's just going to drive a bunch of copy cat projects as
described below if there's isn't some mutually beneficial solution. This
would be negative for both sides, no open source contributions for the
project and duplicated effort all round.
