Some of you might have come across a nice as-you-type incremental
search-through-snip-titles thingy that Stefan Schallerl has been
using on his php/MySQL vanilloid site for about two years now.
(cf. http://wehrlos.strain.at/space/showallsnips)

I've been toying around, coming up with a rip-off for vanilla.
(cf. http://www.agrypnia.org/space/index)

If anyone thinks this is useful and/or fun, a package with a snip
wrapper, a dyna and an external javascript (along with some basic
instructions) is available here:

Cheers,
Markus

P.S.: Since my code is not only dirty, but, on top of it, highly
unoriginal on my part, I'd like to mention that I'm posting this on
Stefan's specific request to share with the vanilla community. So,
thanks again, Stefan! (And thanks in general to all the vanilla
developers.)
