I guess you mean let a relatively smart O.S. do the remapping for the 
dumb ones?
If you have the "dumb" machines behind a FreeBSD router, I think 
IPfilter, and its ipnat utilities can do the trick. I vaguely remember 
that I read it can do it in the documentation when I installed it, but 
I'm not sure what configurations exactly it supports. You should consider 
just waiting for the DNS propogation though, because IPfilter is not that 
easy to master...
