Effects of Very Short TTLs

[Boyd Nation]

We have a small DNS setup that requires the ability to make dynamic changes
that propagate fairly quickly.  I know, or at least I think I know, that
setting very short TTLs, on the lines of five minutes, will cause an
increase in network traffic, but that's negligible in this case.  Are there
any other effects that I should be aware of?
