Sounds like a good idea.

I have actually used jails, just have never set one up. Now will have a 
machine where I think it may make sense.

I like that idea. Specially for files one does not expect to change.
I already have a little script to use mtree to compare directories.

How about CPU overhead?
I like the concept of a jail, but in the past I always wondered if the 
extra complexity and CPU overhead were necessary for my needs. I think a 
current box I am setting up is the first time I think it make sense.

I will have both confidential services/data AND at the same time need to 
serve an app through http to the public. In an ideal world I would like 
two machines, but given how little load I expect to have on the machine 
it's hard to justify.
