Yes, DNS already has a facility to allow for multiple machines to be
considered capable of providing some service, either mail exchange (MX)
or providing the names of servers which can identify a host.

MX records are probably closest to what you want, since they allow for
multiple machines to be specified as mail exchange hosts with weighting
for the preferred and non-preferred hosts.

There are also Well Known Service (WKS) descriptions for hosts (e.g. ftp,
telnet, etc...) which would be analagous to advertising WWW, WAIS, Gopher,
etc..
