Two SSH servers on the same machine

Greetings.

I have a chroot jail used for mod_perl and PostgreSQL development to 
which I have assigned (in my head, to segregate services) a virtual IP. 
 Outside the jail, one OpenSSH server runs, and I'd like to run another 
inside the jail.

The problem I'm facing is that I want the jailed SSH server to use one 
IP and the un-jailed SSH server to use the remaining IPs on the machine.

I'm familiar with the ListenAddress directive, but this doesn't seem to 
be a solution to my problem because one of the un-jailed IPs is dynamic.

My ideal solution would be to tell the un-jailed SSH server to "use all 
IPs except 192.168.171.100", but I don't know if this is possible.

Here's a synopsis of the configuration.

Un-jailed IPs:
eth0    a.b.c.d          dynamic
eth3    192.168.171.65   static
lo      127.0.0.1/8      static

Jailed IP:
eth3:0  192.168.171.100  static

The machine is running OpenSSH_4.3p2 Debian-9, OpenSSL 0.9.8e 23 Feb 2007.

I'd appreciate any configuration tips.  Thanks!
