Nevion Fastbrowser

Adobe air applicaton to browse gui of cPorcessor, nSure and Video Gateway products. The fastbrowser will cache the gui files so that download of the gui files is only needed once. This will help out browsing units on slow IP links. If you have the Fastbrowser already installed you might have to de-install the older one version before installing the new version as it is not signed with a "trusted" certificate.
