But I really don't want to pass all of my personal traffic off to a random new startup's server

And rightly so. Just use EasySMS for the SMS thing (it runs entirely on your phone, no third party involved) and one of the six dozen Filesharing/Samba apps that run over Wifi without going through a remote party (personally I'm using the samba app with the red icon, don't recall the name right now).

Sorry @shynk, but your app is broken by design and the proper solutions have been available in the app-store for years.

Another option for SMS from your computer is to use Google Voice. If your with Sprint you can link your number and call and text from your browser.
