Nikolai, Adobe AIR has it's own application installer, for installing both AIR (if it's not already installed) and the AIR desktop application itself, including totally automated process for updating already installed AIR applications to newer versions. SQLite is already bundled into AIR - which does not require the user to install it separately. So, in order for AIR apps to use CouchDB instead of SQLite, the least clumsiest process (short of Adobe bundling both) is to have an AIR application itself install CouchDB (after letting the user know). Thereafter, starting and stopping CouchDB must be totally seamless to the user.
For Adobe AIR, there is no need to include the Firefox web component because it already comes with an embedded copy of WebKit. With that in mind, would an AIR installation be as simple as placing those Couch 1.0.2 pre-built binaries into a folder? In any case, it certainly sounds as if an AIR based CouchDB install would be a simpler sub-set of what you did for .NET. My problem is that I am not technical enough to do it myself. Thanks again, Zdravko
