Does venet allow a VPS to open a secure VPN or tunnel with another host and keep it really private wrt other VPS ? VServer does not seem to allow that yet.
In OpenVZ each VPS has its own network, so VPSs does not see each other's traffic, so there is no need for a VPN connection between them (still, no problem doing that).
An interesting feature in VServer is what they called unification: secure hard links between identical executables and libs between vservers to save both disk space and memory. Has OpenVZ a similar feature?
This can be implemented by mounting, say, /lib and /usr read-only from the same directory for all the VPSs. Another solution is available in Virtuozzo (and it not yet available for OpenVZ).
what exactly the commercial virtuozzo adds to OpenVZ?
Differences between OpenVZ and Virtuozzo, they are outlined
