Hi,
I'm the XWiki project lead and would be happy to answer any questions
you might have on XWiki and how it could be used for the eclipse project.
Concerning LDAP and load balancing:
1/ There is a indeed an LDAP module in XWiki and it's very easy to
change/modify any authentication as it is well separated in classes
which can be loaded at runtime from the configuration. Single sign on is
therefore possible..
2/ Concerning load balancing, XWiki does not yet run on load balancing
but it has been architectured so that it should be fairly easy to do the
work. Session replication is not needed at all as XWiki doesn't put any
information in sessions which needs to be replicated. The only issue is
with caches which need to be synchronized.. For this XWiki users OSCache
which allows to broadcast cache invalidation (on edits) on a cluster.
There are a few caches which are not yet put in OSCache caches and would
need to be modified (but that's not too difficult). From there it's
mainly configuration and testing.. There was already interest by a
company to make it work on a cluster.. If there are testers it can be
fairly easy to provide tests builds for which we could get feedback
(testing is actually what's the longest for this).
About a few additional reasons why XWiki could be an interesting choice
for Eclipse:
- XWiki is highly skinnable and you can completely control the look and
feel..
- it's possible to setup XWiki as an XWiki farm, which means you can
have separate wikis running from the same servers.. It can even be setup
to allow to "create" wikis by copying a default wiki..
- XWiki is used by two teams at IBM (contacts available if you want !)
- XWiki has a powerful roadmap ahead (Eclipse client, offline usage and
replication, wysiwyg editing, charting, svg, applications, etc..)
- XWiki supports small application development using forms and scripting
which you won't find in any other open source wiki (this is what
Stéphane is using on http://club.mandriva.com)
- XWiki is java which means it can move to be an embedded solution
inside Eclipse
- The programming system of XWiki allows to move many things to wiki
owners (for example each wiki can have it's own skin which is editable
online through the xwiki form interface)
Anyway, don't hesitate to ask any questions about this.

One of our requirements is that the Wiki software must behave in a
load-balanced environment. How do these apps maintain state if, say,
your "edit this page" request is is sent to one server but your
"publish this page" request is sent to another server?
More specifically, problems occur when session state is maintained in
server RAM. I'm not a Tomcat expert, therefore configuring shared
sessions accross servers doesn't appear to be a trivial task, and
anything I do to Tomcat (deploy web apps, compile from source,
whatever) needs to be replicated and maintained across servers in the
cluster.
This bug explains a bit about the requirements we have:

I still like Wikimedia over Xwiki but that's just my opinion.
ok! But that'd be worth comparing XWiki and Wikimedia roadmaps to see
where we might be one year ahead from now!
In the frame of Phoenix possible usage, this link about wiki engines
comparison might be relevant (both MediaWiki and XWiki are present):
http://en.wikipedia.org/wiki/Comparison_of_wiki_software
BTW, there's also an Eclipse plug-in for Wikimedia:
http://www.plog4u.org/index.php/Main_Page
and one for Confluence:
http://blogs.atlassian.com/rebelutionary/archives/000410.html
and one that supports a few other wikis:
http://eclipsewiki.sourceforge.net/
though none of these are WYSIWYG, if that's important for you. After
using MS Word and various other tools (editme.com, htmlarea, etc.)
for WYSIWYG html editing, I'm sticking with plain text for now.
However, this looks nice, at least on paper:
http://vex.sourceforge.net/
Vex looks very promising indeed, thanks for the link!
There's no rich editor for XWiki yet, but there's this online DHTML
editor available: http://www.xwiki.org/xwiki/bin/view/Dev/DHTMLWysiwyg
