you know, this is a "funny" topic: it's not something i figured would be 
overly critical but it's something a lot of people want to do from their 
javascript plasmoid. so i had (obviously mistakenly) delayed this feature 
until the 4.5 release this summer (Javascript API v2).

short story: there is no good way of doing it right now.

longer story: i or someone likes me needs to write a small C++ Service plugin 
(does not need to be related to a data engine at all, in fact, though it 
probably could make sense as part of the Notifications engine as well) to do 
this. 

sorry for the horrible news. :/

the source name is what the entry is called in the DataEngine. the idea is 
this:

you have a DataEngine and your are connected to one of the pieces of 
information it provides. in the Hotplug engine (which announces events like 
when you plug in a USB stick, for instance) this might be a disk drive. 

then you want to interact with it. in the Hotplug engine case, maybe you want 
to request that the disk be mounted. at that point you ask for the service for 
that source, and you do so by asking the DataEngine to give you a service for 
the source by that name.

a concept we don't have is a "default service" for a DataEngine: you always 
need to ask for the service for a given source.

in the case of a service-without-a-source, as in the case of notifications, 
one can ask directly for a Service without going through a DataEngine.

for notifications, that Service needs to be written still.
