Can you perhaps provide us a link to the VHI program so we might take a look? It is interesting that you don't like the idea of a subscription service. Is it a cost implication? We have seen many for as little as £70 per annum which is a lot less than a single PhysioTools product yet includes much more and is continually updated and accessible from any PC at anytime.
Any thoughts on what specifically it is about the subscription that you don't like?
