This is also a question about how heavyweight you want your 
virtualisation.  Many people won't settle for less than VMWare style 
whole machine emulation and complete separation.  Vserver, et al are 
much lighter weight still and your proposal is extremely lightweigth, 
but hard to figure out how it could be implemented if multiple users are 
involved...?

Simply hard linking all the similar jail files together will apparently 
cause the non code pages to be loaded only once?

Note that if you share code pages between instances then you need to be 
happy that any jail which can corrupt those pages gets to run code 
across all jails... :-(
