that is gonna be the hard part for me.

thats my point :)

An other topic which leads me to time dependency ... a dep which is not to be

no; I found vserver hard to install on Gentoo, hard to conf on Debian, and 
several
friends told me that they are not that much secure.

I really think that xen on Alpha would be EFFICIENT /and/ SECURE.
