I'm looking for a desktop publishing platform for Mac, Windows, and Linux that is closely tied to PhoneGap in terms of the concept. I know that there's Titanium for Desktop (TideSDK?) but as far as I've used it before, it requires the end-users to download a big 70mb-ish runtime file once. What I liked about PhoneGap is that it doesn't require any of that (it works out of the box). I'm looking for something similar, only, instead of being meant for the mobile development, it 's targeted at desktop application development.
Perhaps I failed to mention it but if you are not aware of what I'm specifically talking about, I'm talking about an environment of sort that will let me code via an HTML base and output a native for said platforms. Both TideSDK and PhoneGap does this.
