1) I'm looking to find who supplied 10East with the script ... pretty sure it's free for credit.
2) I'm actually hoping to use JS client side with PHP server side ... working up an extended blog-type system. (Have you gotten into full-text searching? "Transparent inference" has whetted my appetite for this task.)
3) My university supported cgi at least partly by providing cgi-wrap ... no symlinks though, which caused some problems.
good luck
