The underlying asio library itself is general purpose - so it is not
just for STUN/TURN.  TURN is very compelling now that WebRTC is taking
off and uses TURN by default from the browser.

To give another example, asio has been used as a foundation for the
websocketpp suite, which enables both client and server websocket
development

asio itself is a header library for asynchronous, event-based programming

It comes in a boost version and a non-boost version.  This is the
non-boost version, so it is likely to have less impact than the boost
version.  I confess the full solution with SIP + TURN + SSL is a little
top heavy though, a device with 32MB RAM may not be enough, my WL-1043ND
couldn't handle it all.  On the other hand, one of these jumbo routers
(I went and got a Buffalo WZR-HP-AG300H with 128MB RAM) is quite
suitable and can run a full WebRTC stack as a convenient alternative to
Skype.

Here is a trivial asio example:

I've made up a patch against OpenWRT, to bring this into ceropackages do
I need to adapt the patch or you can easily use it as is?  Please find
the Makefile attached.
