I'm not quite clear on what exact kind of implementation you had in mind
or what your testing, but I would recomend, ethier using gentoo (the
metadistrubtion allows for some unique security measures) or freeBSD 5.x
series (the jails can allow for some new implementations, and the distro
has a proven record of security) or slowaris (since you can use solairs
to actually segment CPU memory, ect ect, esiientially make nested
installations independant of the exisitng install)
