I think you've, basically, got it, except that there can be multiple "source 
IPs" (in your terminology).

I'm a bit of a stickler for proper terminology, so I'd say it this way:

The LDM server listens for incoming connections on the interface corresponding 
to the IPv4 address given in the LDM registry. If this value doesn't exist or 
is "0.0.0.0", then the LDM server listens on all interfaces.

A downstream LDM process connects to the upstream LDM server on the host 
specified in the corresponding REQUEST entry in the LDM configuration-file. The 
host can be specified as either a hostname or as an IPv4 address.

So, in answer to your original question, yes, the "source IP" IS hard-coded 
into the LDM configuration: it's the host specification of a REQUEST entry.
