While Data View Web Parts may be the coolest thing since...well, Sharepoint...the only way to implement them non-programmatically is with Frontpage. Despite how you may feel about the tool itself, using it to edit pages has the major drawback of sending one immediately into Ghosting hell. The more you edit the worse it gets. What to do?
Fortunately, the answer is simple. When deploying DVWP's, set up a test area or site that is removed from portal navigation (you can always delete it later). Once you've created your web parts page/area/site with Frontpage, you can simply export them to disk, then import them into the correct page. This prevents ghosted pages from running amok in SPS/WSS while still allowing the use of those wonderful DVWP's.
