it should be; however, there is no scripted Service plugin support like there 
is for DataEngine, Applet and Runner. i'll be adding a ScriptEngine class for 
those in 4.3. but you should be able to provide a Service from a DataEngine in 
Python, though again that may not be exactly what you wanted; a Service 
without a DataEngine may be more what you're looking for.

well, sources are created on demand, though. there are a few million twitter 
users; we don't load everyone's account in the TwitterEngine ;) 

when a DataEngine gets a request for a source that does not exist yet, it is 
given a chance to create that source on deman in sourceRequestEvent.

so in such a situation, your DataEngine would only need to create the sources 
requested.
