[sakai2-tcc] [WG: Licensing] Sakai 2.9 Planning in Confluence

[Nate Angell]

rSmart releases its Sakai distribution free and open source, so we are
not concerned by the inclusion of an LGPL component like JGroups.

As long as JGroups is included in Sakai as unmodified, standalone
code, we don' t see an issue, nor do we think those who might make
proprietary distributions of Sakai would find it to be an issue.

If you are distributing LGPL code (source or object), you definitely need to distribute / make available the source code, and you need to make sure people have the freedom to modify it.  That's easy enough for LGPL code that is being distributed along side core Sakai code that is subject to the ECL.  But it can be a problem for people who want or need to offer a version of Sakai that they've supplemented with proprietary code of their own.  They'll have to make sure their distribution preserves the ability to modify the LGPL code, and depending on how much LGPL code there is in total, and how it's used, you may end up creating problems for your integrators / more commercial partners.

The more LGPL code there is, and again depending on how it is used, you can create a situation where the LGPL terms start being "viral" even though we're talking about the LGPL here, not the GPL.
