I may be missing some subtlety here, but it sounds like you are looking for a jQuery (Javascript) autocomplete script with an AJAX back end. This would load the vocabulary in the background, typically starting at page load.

This works fine as long as the vocabulary is of a reasonable size. If we are talking tens of millions of entries, it is not going to work so well, and if you have to look up terms in real time as you type, I don't know of any client/server tool that will be fast enough.

Thanks,
