Thanx Roger.

@James, see https://www.torproject.org/docs/tor-manual-dev.html.en and
look for SOCKSPort [address:]port|auto [isolation flags] .

SocksPort 192.168.1.1:9050
SocksPort 192.168.1.1:19050

works (when removing SocksListenAddress if you had that).

I configured two different browsers, one to use port 9050 and another to
use port 19050. I visited http://check.torproject.org/ seven times (every
time killing tor and starting it again) with the two browsers and two
times got the same result (same IP of exit node) in both browsers.
