Excellent.  Could you please provide me with a link to the conference, so
I can produce it in my next activity report?

I see.  Hopefully we can have native support for OBS in Galene once they
implement WebRTC, but I wouldn't hold my breath, the OBS team don't seem
too interested in improving their networking stack.

Perhaps.  It could also be due to a single hotspot -- perhaps the crypto
(the RPi doesn't do AES in hardware), it could be slow I/O, or it could be
the locking implementation that is different on 64- and 32-bit.  I've got
a 32-bit ARM board lying somewhere (a Beaglebone, thanks Dave), but it
doesn't have Ethernet, so it's tricky to test.
