Tell your manager: when it will be then it will be. Be glad that there is at least some dude development at the moment. It wasn't so many years ago... If you need Web interface now, use old dude version where Web interface works.
Thanks Jarda,
I am well aware that the development is happening on my side as i have been using v4 for a long long time and still have it running on certain remote sites.
Reason i have needed to move to v6 is due to performance issues i was experiencing on v4 with the size of our environment that it was monitoring. plus on certain devices i would end up not being able to log into certain devices because of 'stuck connections' to devices
