If anyone gets ejabberd running correctly using those instructions, 
please let me (or just the list) know.  I posted a while back with a 
list of issues and received no response.  I got busy with other things. 
  This thread brought it all back.

Here's a synopsis:
The ejabberd 1.1.4 stuff won't even start, dying with some obscure 
erlang error.
The ejabberd 2.0.0 beta stuff is a whole lot more promising.  It 
actually runs.
I believe the "setting up shared roster" roster is not correct, and I 
had every intention of updating the wiki as soon as I figure out what 
was wrong... that never happened.

In short, following those instructions will make it so XO's rarely see 
each other, much less share resources.  I started fooling with those 
values in the shared roster.  It seems that "Displayed Groups" needs to 
be set to the value of the identification (what you called it when it 
was created) not the Name, which seems to be a pretty print name.  The 
examples at:

http://www.ejabberd.im/shared-roster-all and particularly
http://www.process-one.net/docs/ejabberd/guide_en.html#htoc64

seem to indicate this.

When you do that, XO's can see each other 100% of the time, but shared 
resources do not display properly at the remote XO.  (You can invite 
others to share and the actual sharing works properly) In the end the 
closest I could get to having everything right was setting my shared 
roster as such:

Shared Group:     Everybody
Name:             Online
Description:      <blank>
Members:          @online@
Displayed Groups: Everybody

This issue is echo'd here: 
http://wiki.laptop.org/go/Talk:Ejabberd_Configuration by another user I 
commiserated with.

If anyone is interested in pursuing this, I can bump my previous post, 
but right now its not a high priority for me.
