Per Word Auto-Complete

Im looking for a script that performs an auto-complete in a textbox, but does it per word (not replace the entire textbox).. so if the input is "hi my name is lo" it will check the array for lo and do an auto complete on that.

anybody have any ideas?

thanks

I'd research methodologies of auto-completedness and fuse them maniacally through trial & error. :D
