Think very carefully about using a subdomain of your business domain
for this. Do some googling about what happened to 'monkeys.com' for a
case study in what bad things can happen.
Do you have enough DNS bandwidth for this? Bear in mind that queries
for the subdomain will hit the main domain servers first, so you'll
get double traffic for each subdomain query, which you won't be able
to make go away once the existance of the dnsbl gets into the wild,
even if you've shut it down or moved it.
