..so frames somehow aren't delivered..

Ok, as a general hint I would try enabling debug (either calling to
vortex_log_enable, or setting environment variable
VORTEX_DEBUG=1 ./your-app). This will give you lot of output...

You can also check [1] and [2] to see how those examples are implemented
to get hints about what is failing..

I thinking about ways to make frames to be not notified is to not set a
frame received on the particular channel/profile/ctx, or to send some
replies with some of them missing (ie, sending replies 2 and 3, without
sending 1), and having vortex_channel_set_serialize activated...

Nice Martin...

Thanks!
