However, the real point was that HEXA2 claims no downloads are needed. Not everyone will automatically update and the threat is there even when not using the web conferencing service. Additionally, hackers keep finding new ways to get in, so Adobe has had to constantly update with new versions.
Surely it would be better if HEXA2, Netstairs and the other Moradi web conferencing platforms didn't require a hacker-prone software to be loaded on a users computer.
Another problem with the AFP is that I don't believe it is supported on iPads or iPhones. It seems to be obsolete technology that Adobe is backing away from.
