Re: I love the smell of vaporware in the morning!
Strictly speaking it is not vapourware as the software does exist *but* it is debatable if it is 100% resistant to copying data out of it.
Apart from Phone apps to OCR the data off a screen or simply taking a photo, I am sure some miscreant will find a way to run some code in a browser to exfiltrate data.
The issue is not with a browser but with the 1000's of ways to write code to do the *same* thing, which means you may block one way to copy data but miss another.
I am sure that this will be breached *eventually* ....... as per usual !!!
