Roman Mamedov:
Another idea that I proposed some time ago is raising the relay-per-IP limit
is there a trac ticket for this already?
AFAIR that limit primarily exists mainly to increase the price for Sybil attacks, but since they would be trivially detected (i.e. by OrNetRadar), I do not see why increasing that limit would hurt (much)
on the other side: Is there an actual demand for increasing that per IP limit?
If you have been impacted by that '2 instances per public IPv4'-limit and would benefit from an increase please speak up
