kyle, you and ricci have a great site in the works. you might consider adding a derived data column for swept volume (2x xmax * sd), as there are lots of folks who would like to sort on that.
also, in order to spread the work over a larger group, is there a format that you could accept additions to the list, such as a comma delimited text file or something using the data-bass standard units?
i'd be happy to kick in a few.
edit...nevermind, i just checked and winisd files can be opened as text files. all you need is a simple script to extract the data and you can have every winisd file moved into your databass. a rent-a-coder should be able to write the script to extract the data for $25 or so. then just copy all the drivers that you want into a directory, run the conversion script, and you are done.
