This is what You're suggesting, am I right?

def wait_for_tcp_port_to_open(host, port)
        loop do
                scan_result = `/usr/bin/nmap -n -sS '#{host}' -p 
'#{port}'`
                return if scan_result =~ /[\s\t]open[\s\t]/
                sleep 1
        end
end

Not a nice solution, but works...  Any other idea?
Maybe one in pure Ruby?
