Your license will be valid for all future versions of the product. You will never be charged for upgrades!
Vypress Tonecast is licensing on per listener (receiver) base. To run a broadcasting you should purchase server license that will cover all listeners (no matter what software it running - standard Tonecast Receiver or a WinAMP plug-in).
