I'm curious Imeo do you know how exactly how you'll be making VIR compatible with JustGG?
they're useful to some point if you wanna look at said device in more detail than just a the sellers description and some photos.
the first question is easy Seek. A new tube, almost same as Proteus (but fatter) that will include VIR and will fit on justGG between extension and collector tank. It will have male-female threads. As for the software, it has to change.
I simply agree on the second issue
