generate word docs

Summary: I have to create a word document on the fly. what's the best way to go about it? Okay so I have a client that would like something output to a word document. I already have HTML and PDF versions... I'm trying to figure out the best way to do this. I am already aware of the open html in word hack. The way I see it, these are my choices: 1) Use the hack that I'm really don't like. It never looks quite right (which is the whole point of this). 2) Move everything over to a windows host and use COM. 3) Somehow convice host (hurricane electric) to run PHP5 CVS w/ Sterling's mono extension, and use .net to create the word document (does mono support that class yet?). I hate C#. VB is even worse. 4) Find an open-source library that writes word documents (quick search revealed nothing...), write an extension for php. 5) Find a spec for word docs and write a library in php 6) find a spec and write a library in c, then create php extension. I'm willing to do this, but it would take a long time... 7) Tell my boss to sod off (politely, though), it's not currently feasible... I think this is what he's expecting, anyways. So, does anyone have any suggestions/comments? Anyone know where I could find a library (in c or php) or a spec? I'm kinda thinking aloud here hoping someone will prod me in the right direction...
