Synchronisation Mozilla Thunderbird Lightning
There is no project to sync Egroupware and Mozilla, though Egroupware and Thunderbird both support some common protocols. Also Funambol has a client program to Sync a Mozilla calendar using SyncML (http://www.egroupware.org/index.php?page_name=sync&lang=&wikipage=SyncML) which is supported by Egroupware, though untested. It is possible to write a xml-rpc or soap plugin for mozilla for syncing, though no projects have started yet. See below for more information.

Mozilla does not support writting to an LDAP database, so only read access is supported.

It seems to work rather well, synchronizes calendar, tasks and addresslist.
xml-rpc/soap
Egw provides a SOAP interface, that means you can call via the SOAP protocol quite a lot of functions of Egw (exactly the same ones as via the XMLRPC protocol if I am right). And Mozilla also provides a basic library system that allow you to do interact from javascript to remote webservice via SOAP. see
http://www.mozilla.org/projects/webservices/ and there is even an oreilly book about it: http://www.oreillynet.com/pub/a/javascript/synd/2002/08/30/mozillasoapapi.html?page=1
So combined, this means that you can design html pages for Mozilla in which you use javascript to call functions of Egw. It is a methodology that nowadays is selled under the hype word AJAX.. So if you are very handy with javascript you could reproduce the google calendar interface but have it working with you Egw server
