Just an update on Kword exports as this thread is a little outdated now.
I see that you can save Kword documents as Microsoft Write, OpenOffice, HTML, rtf, WordPerfect and AbiWord.
Some of these can be opened directly in MS Word by the receiver and saved as .doc, while your other applications can save your document as .doc like OpO and possibly abiword.
So it's quite possible today to create MS Word compatible files and also .doc for that matter out of documents composed in Kwrite, just not in one process.
Perhaps some individual comes up with a kwd2doc application before Koffice?
Besides I find elements from koffice crashes so much more often than OpO (never). Example of just now on a freshly installed kword while opening a .rttf documents saved from OpO. I don't trust koffice for this reason as it usually crashes during the task. Has done this since 1999 and still does it over several distroes and versions etc.
