[syslog-ng] simple subscription based interface?

Hi, The use case is a crystal box: everything (but keys) are public in the system, including logs. So I want to configure syslog-ng such that anyone can connect to it, and receives the logs. The simpler the interface, the better. I also would like to have some limit on the number of concurrent clients. Any way to achieve this with syslog-ng without using an additional stomp or amqp server? My syslog-ng version is 3.5.6-2. If there is a need for a message broker, could anyone suggest a free or dirt cheap one in the cloud?
