i'm not sure it maps to the concept of DataEngine very well to be honest, 
which are meant to be multi-reader. the grouping classes in libtaskmanager 
really pretty specific to the context of the consumer: what screen are you on, 
should it show only what's on this desktop, etc..

some ways this might work out ok, though, is to provide "group sources" that 
would publish lists of tasks that belong together, e.g.:

source = tasksByProgram
ungrouped (.. list of tasks .. )
kontact (.. list of tasks ...)
konsole (.. list of tasks ..)
etc..

where this starts to fall down, really, is when one wants to sanely mix and 
match ("tasks by program name, on screen 1").

one could create a generic service that would take a set of a params, set up a 
(or use an existing) source (so all consumers using the same grouping 
configuration would share the same source) and return the name of it as the 
result value.

manual grouping and sorting would be even more difficult to map sanely.

i think that if this work is done, it really ought to be done with a clear use 
ase in mind which is done in parallel. otherwise it risks being a good amount 
of work (and added complexity to the engine itself) that never gets used.
