That sounds reasonable, thanks :)

It does appear to, once someone enters a conference:

root@video:/var/lib/galene# ss -ntpl | grep galene
LISTEN    0         128                      *:443                    *:*        users:(("galene",pid=793998,fd=6))                                             
root@video:/var/lib/galene# ss -nupl | grep galene
root@video:/var/lib/galene# mv data/ice-servers.json .
root@video:/var/lib/galene# ss -ntpl | grep galene
LISTEN    0         128                      *:443                    *:*        users:(("galene",pid=793998,fd=6))                                             
root@video:/var/lib/galene# ss -nupl | grep galene

So nothing, but after entering a conference and turning on video it does
appear to enable itself:

root@video:/var/lib/galene# ss -nupl | grep galene
UNCONN    0         0              45.145.95.8:1194             0.0.0.0:*        users:(("galene",pid=794316,fd=9))


It even turns itself off again if I restore the file:
root@video:/var/lib/galene# mv ice-servers.json data/
(enter conference)
root@video:/var/lib/galene# ss -nupl | grep galene

I like it - "sufficiently advanced technology being indistinguishable
from magic" and all that :)
