[IronPython] Distributing a commercial application which hosts IronPython 2

[Jimmy Schementi]

Angus,

You can definitely redistribute IronPython assemblies in your application, and that's the best way to use IronPython on both the desktop and Silverlight. I'd simply have a "IronPython" folder in your app, and in there you put the assemblies and the license.txt, containing the Ms-Pl text. Resolver Systems does this with their products, so maybe Michael Foord can give you some advise.

The Ms-Pl license that IronPython uses is "non-infectious" ... as in other code that uses does not need to conform to the same license. Reciprocal licenses, like the Ms-Rl or the GPL, require anything using the code to have the same license.

Hi folks,

(Sorry if this is an inappropriate place to ask this question. I
searched the archives, but prior license discussions all seem to refer
to the old license.)

What is the "best" way to distribute a commercial application which
hosts IronPython 2? Is this even possible?

My original plan was just to require users to install IronPython first,
and reference the assemblies from the IronPython installation. However,
because IronPython doesn't install anything to the GAC, and because of
.NET Framework limitations about loading assemblies from outside the
AppDomain's base directory, this is impractical.

It doesn't seem like Silverlight installs anything to the GAC, either.

 From reading the MS Public License, it looks like it might be possible
to distribute the IronPython and DLR assemblies along with our
application, explicitly under the MS-PL. While concurrently the
commercial/proprietary parts of the application (including our hosting
code) are distributed under our closed license. Is that correct? I can't
seem to find a clear answer anywhere. Are there any examples of how to
correctly structure a license agreement, in this case?

I would very much like to allow people to use IronPython from our
application (I'm very impressed with both the language implementation,
the performance, and the hosting API), I'm just unsure how to do it.

Thanks in advance.
