I think it should be enough,

zones/controllers/ipam/dns should be small, vnets + subnets should be the biggest part.

around 50bytes by vnet  and around 80bytes by subnet with all options.

so around 150bytes for 1vnet+1subnet.,  this should give use around 3000vnets/subnets.


I think it's enough the current cluster size (20-40nodes max), so maybe 5000vms max
by cluster,  3000vnets should be enough.

sounds good to me. 

But, do you think complex setups could outgrow the 512k pmxcfs file limit for 
big setups?
