It came to our attention that we were sitting on several unused RVskin dedicated licenses.
As long as all our servers come now with RVskin included, we don't need anymore these licenses.
I just talked with Pairote Manunphol, RVskin owner, and their EULA allows to transfer licenses. (Trouble ticket track link available through PM request).
All licenses are expired and support will have to be renewed ($29/year/license).
We are asking $39 per license. Which is still a great value after support renewal as long as these licenses are sold $99.
Don't know if a trouble ticket has to be open to verify the eligibility of these licenses. As far as I know, RVskin uses an online license verification process and can't be installed on several servers.
