Finally someone that takes my concerns serriously, thank you!

I agree. Using chroot could offer the functionality Im looking for.

I will try the chroot model for now, I have a feeling that this wont be enough 
though, but we will see. Something in the chroot manside got me puzzled:

Only the super-user may change the root directory.

Note that this call does not change  the  current  working
directory,  so  that `.' can be outside the tree rooted at
 `/'.  In particular, the  super-user  can  escape  from  a
`chroot jail' by doing `mkdir foo; chroot foo; cd ..'.

I will have to figure out the consequences of this odd behaviour, 
it certainly dont sound very safe at first look. 
Maybe jail is much better, but it seems to require porting as you said.
