It is relatively wide spread. However due to its nature, it neither defines a
standard way of detecting "remote" apps with osc interface, nor does it
provide a standard way to introspect. So for example a pair of apps that do
gui->backend split will work because both written by the same author(s) know
how to detect and talk to each other. For apps written by different authors, it
gets difficult. And its basically impossible to write any "generic osc sender

If osc was a protocol that has a centralized distribution like jack does for
audio and midi and alsa-midi does for midi. But most osc usage happens over
udp, that is network. That is fine to have gui and backend on different machines
but completely incompatible with qjackctl providing a "central patchbay" (not
that this concept would make any sense for osc).
In general it would be possible to send osc over jack-ports. Jack supports
generic port types and osc isn't actually fixed on using udp. But the problem
is: when app A sends osc across a jack-osc-connection, who guarantees that app
B can actually do something useful with it? osc just defines a way messages are
sent. It doesn't care about specific messages, it doesn't care about answers,
it doesn't care about the transport...
BTW: For entry into osc, python and its liblo-interface should give you a good
