Whether you do it on 2LD, 3LD or even 4LD level, it seems to work, so
why not on TLD level? It's mainly a matter of horse power, I'm quite
sure BIND is capable.
But, if one restricts applications to groups of applicants rather then
allowing individual applicants, one would avoid excessive
proliferation.
