"The theory behind SRV is that given a domain name, for instance, example.com, and a service name, for example, web (http) which runs on a protocol (tcp in the web case case), a DNS query may be issued to find the host name that provides such a service for the domain" -from http://www.zytrax.com/books/dns/ch8/srv.html
So, what you will get is a list of host names that provide the service you're looking for. Then, you have to try those hosts until you get a response. What I've just realized is that db_mysql module may not support this...
