Group-office integration.

[Steve]

I've recently been playing with GroupOffice - and am extremely impressed
by it in a number of ways.

http://www.group-office.com/

I'm using the community-edition - partly because I don't think I need
the features offered in the commercial version, and partly because I
have no budget.

I love the web interface - and the 'CRM' approach to the address book is
something I've wanted for ages. That said, I'd like to integrate this
with Thunderbird and Lightning - because native applications remain
preferable for LAN access.

Has anyone here looked into doing this? If both calendar and address
book (I know, wrong list) were integrated, Group-office and Thunderbird
would be my ideal system.
