* ThinkFree Office is a commercial cross-platform application, that includes: Write (word processor), Calc (spreadsheet) and Show (presentation). The suite also has an iPod edition.
* ThinkFree Online is a free version of these applications that works similar to Google Docs & Spreadsheets.
* ThinkFree Server is "a web-based, server-hosted office suite which allows users to edit and create word documents, spreadsheets, and presentation files anytime, anywhere".
I think the most interesting ThinkFree component is the server edition, that could allow Google to create something like Google Search Appliance / Google Mini, or to enhance the two boxes. A server edition for Google Office will be much interesting for organizations, as they don't want to lose control over their information.
"ThinkFree chief Kang [Tae-jin] plans to take a flight to the United States this week, and he may meet with Google officials there to discuss a deal."
