Several people, including myself, are working on a csv module for the Python Standard Library. It is slated to be included in Python 2.3 and is already available via CVS. I will post a new version of DSV that builds on top of this module in the next couple of days. Feedback and bug reports are welcome.
1.3.9 and probably previous versions had a superfluous and expensive function call in the import wizard. 1.4.0 removes this and import times should be cut in half for large files.
Finally got a home page up with a screenshot and some basic instructions.
