Surely you're more experienced than me, but VVP is very widespread and would need several changes ... and a lot of assistance. A new product would surely be appreciated and required, in my opinion, also of interest for software companies that would more chances to sell their products.
For example I would like to solve the problem of virtual IP of VVP used in LAN .. Would allow you see the data logger from any computer in your network, but unfortunately it only works locally: using in LAN, after a few hours the software crashes ... And I was never able to solve it.
Then there are all the little problems with VVS ... In short, a very useful and powerful software, that can not be exploited as it should. And with the new updates will be destined sooner or later to become obsolete and unusable.
A real shame.
