RealVNC heeft een nieuwe versie gekregen van de ontwikkelaars, ditmaal met het versienummer 4.1 waar in een aantal belangrijke veranderingen zijn doorgevoerd. Het programma kan gebruikt worden voor het op afstand bedienen van een andere computer. Dit kan crossplatform gebeuren, bijvoorbeeld van Windows naar Linux en omgekeerd. Je neemt de desktop van de andere computer over zodat het net lijkt alsof je er fysiek achter zit. De release notes laten ons het volgende weten:
