This may be a good explanation for C++ developers of how the API is
implemented, but the reason you went to all the trouble of hiding
the CORBA layer is that users shouldn't need to know about it! So
instead of talking about CORBA in the description for packages like
tango-db, could you include a few words to explain what "TANGO
devices" are (in terms of what they're for)?
They seem to be software objects designed to represent categories of
hardware devices; but if the hardware it's being used for is
particle accelerators, isn't that also worth mentioning somewhere?

Perhaps you mean "representations of device processes"? But you're
taking it for granted that readers understand what a device process
is, and if they're at all like me, they won't.
