Thank you 'api. I have been using zt at the university group of about 60 users. Must say it is very reliable. As for UI, we are OK with it. But one thing is firewall config is too complex. Not enough examples:
Recently I saw that zt-laduke posted a simple bridge tutorial on reddit. Would be great if you made some examples in your wiki.
1. Allow only samba traffic
2. Allow only ssh traffic
3. Allow only RDP
I am sure is kinda popular at r/datahoarder and related communities. May be you need to apply for a GSOC type project - so that academics start using it (will then later get used in corporate).
We have generally been focusing on behind the scenes tech more than GUIs so far.
