Stores like SlideMe powers the market for most roms and for all devices that use aosp (android open source project) that have no google play.
Good news! We have completed your Golden Frog Idea suggestion and VyprVPN is available in stores other than Google Play.
You can now download VyprVPN on Slideme and in many other stores for Android. http://slideme.org/application/vyprvpn
