sounds good, maybe linux-vserver and bsdjail can
share/utilize common code/functionality here?

(will have a look at the code soon)

also interresting enhancements might be

- private namespaces (linux-vserver uses them)
- certain virtualizations (loadavg, ...)

anyway, let me know if you are interested in
any cooperation ...

best,
Herbert
