just in case anyone else ever stopped by with this question and was as frustrated as i was by the offers of "it's just an editor"... dreamweaver mx has some features other than just making pretty pages that i was interested in trying out, so my original question obvioiusly needs some clarification and here is the answer, which i got when i called macromedia...
i develop php applications and my (possibly badly worded) question was relating to dreamweaver's ability to interact with a mysql database for building and testing those apps before they are actually made live.
the answer to my question, *from macromedia* is that only Windows servers support those features...
back to hand coding and manual testing
