Uniformity via Cauchy filters?

Dear categorists, One of my current research projects has drifted into the realm of uniform locales, which is not exactly my forte. As I went to re-familiarise myself with the assorted definitions, I found myself wondering whether one could define a uniform locale as a locale equipped with a designated set of Cauchy filters, instead of uniform covers, or entourages. Does anyone know whether this idea has already been pursued, either for locales or for spaces? Cheers, Jeff. Looking for the perfect gift? Give the gift of Flickr! http://www.flickr.com/gift/
