Answering to Fabian's mail, which came a minute before I was about send a
more verbose answer.

Thanks, too.  BTW where is the git repo, please ?

It did work fine under FreeBSD 7.4-PRERELEASE with sockstat the way you
suggested. 
I modified in src/util/connections.py again to 
RUN_BSD_SOCKSTAT = "sockstat -4c | grep '%s%s' "
(See Fabian's patch.) This works fine, too. Just one cycle less.
Neither of the other options though did succeed in displaying a connection
list.

Can verify this, running arm on a host connecting to a jail's tor controlport
results in this.

An old torrc located in the  host in the same path as the jail,  I
wondered where these odd configs came from. Removing the hosts torrc
gave  
 ### Unable to load the torrc ###
so arm is trying to read a torrc on the host in the location it knows
which is displayed from the jail, but is ignoring the jail flag.
  Sorry for not getting deeper in this right now.

To Fabian, instead of adding another patch:
Running 'pgrep tor' might show  multiple results, anything containing the string
'tor' will present it's pid.

On 7 it's 'pgrep -x' to get an exact match of the argument ,see man pgrep(1).
   
Thanks for the patches !

 
To all :
The working connection list looks great !
