I think it depends a lot on what you mean by an "ELN". As mentioned above, a lot of the Open Source ELNs come out of the Open Science community. There's a lot of stuff being done in the UK by people like Jeremy Frey and Cameron Neylon.
One that hasn't been mentioned in the list above is http://www.myexperiment.org/ which may or may not fit a definition of an ELN.
Depending on what you are trying to do, you might find the following useful to investigate - all of which I've seen used in both Academic and Industrial settings:
- Blogging platforms, especially
- Wikis (especially Confluence, which
isn't free but it can be cheap for
- The standard Office tools
- Especially on the Mac, a whole host
of smaller note taking and organising
I was responsible for the now-defunct OpenSourceELN which we wrote in Zope/Plone and was surprisingly popular given we didn't really put any effort into pubicising it. We looked at reinvigorating a while back it but frankly Wordpress is better than anything we could come up with.
If you focus on what you are trying to do (which is generally content management in some way) and can overlook some terminology differences, then there's lots and lots of things around. The ELN problem isn't that different from other kinds of tools that have grown up to support knowledge workers, with the exception that in industry you start to worry about Patent evidence - but that's mainly a record keeping issue, not a content management thing.
