Integrating Exchange Calendars and Thunderbird - Part II

There's a good route in with Thunderbird.

1. Using the addons manager, add Lightning.
2. Then download the EWS addon from here
3. Restart Thunderbird
4. Add a new network calendar, choose Exchange 2007/ onwards as the type, and use auto discovery to find your exchange server 
5. Bingo!

Integrating Exchange 2010 calendar with Linux - The Horror

It would be possible to publish the .ics file, then miport it.  But our admin staff won't allow this.  So... 

1. Find a Windows machine with a Staff install.
2. Got to Outlook, Sharing, Pulish to Webdav server, and publish to http://www.icalx.com/public/mattstudley/Matthew_Studley_Calendar.ics
3. Now import into Google Calendars... 
4. Or into Thunderbird, etc.

This isn't a full integration.  But at least will allow me to see the events that people past in my calendar.  

What I need is full integration - I want to be able to publish my Google Calendar events to my outlook calendar so people can see my availability, and I want them to be able to insert items into this calendar so that I can see them in Google Calendar.
