Actually when we tested against lightning at the last calconnect  
interop it went well, there were some hickups because they were  
implementing scheduling and assumed our server supported it, but in  
the end they were able to publish. We don't have instructions, which  
is what the no part is for. To be totally honest I don't know what is  
going on with Sunbird and Lightning since I haven't spoken with any  
of the mozilla calendar developers since before that blog post by  
Mitchell Baker about the future of thunderbird.
