Here is a simple question for you.. why you shouldn't be automating office on the server side..here are the options :
1) Because you promised your boss that you won't do it ?
2) Because gravitational pull of moon can have a negative impact on your solution?

With Office 2007 we introduced a new document format docx, or Open XML, The Office Open XML Formats are based on XML and ZIP archive technologies. The new file format in Microsoft Office Word 2007 divides the file into document parts, each of which defines a part of the overall contents of the file. You can easily create, change, add, or delete data in a Word 2007 file programmatically or manually. Here is how to create an Open XML file without using Word http://msdn2.microsoft.com/en-us/library/bb264572.aspx .
You can do the same thing programmatically, here are a couple of links that you can follow
So, using this method we can create a docx file which is a native format for Word 2007. Now, the only problem remains unsolved is; how to use this format with the older versions of office! And we already have a solution for this problem. You can download and use Microsoft Office Compatibility Pack http://www.microsoft.com/downloads/details.aspx?FamilyId=941b3470-3ae9-4aee-8f43-c6bb74cd1466
By installing the Compatibility Pack in addition to Microsoft Office 2000, Office XP, or Office 2003, you will be able open, edit, and save files using the file formats new to Word, Excel, and PowerPoint 2007. The Compatibility Pack can also be used in conjunction with the Microsoft Office Word Viewer 2003, Excel Viewer 2003, and PowerPoint Viewer 2003 to view files saved in these new formats. For more information about the Compatibility Pack, see Knowledge Base article 924074.
