Well I wondered the same thing, so guess what, i clicked on the link and found out!
I may try this, it almost looks fruity, but if its BASICALLY RHEL/CentOS at the core, the stability should be there. I run most servers in level 3 anyway, so looks would be moot. I like that there is a built in web UI (I usually put WEBMIN on my CentOS installs anyway, so Id be curious to see what that entails, and if it is any better), built in VPN, I like that, though it would depend on what it offers.
I think I'll download it and see if I can find out more about it and maybe post back tomorrow.
