sure, I've certainly used IP to provide a useful mnemonic for the "role"
of hosts within a cluster.  but I'm worried about your use of "location"
here: HPC clustering is normally done in a single location.  if you're 
into clustering across geographically significant distances, then your 
latency becomes high and therefore you're probably doing grid stuff.

wifi, let alone 3g, would introduce dramatic issues of latency and
bandwidth.  I don't think I'd that clustering.

eh?  nothing much has changed in HPC clustering - incremental improvements
to networks is all.  you might be more interested in ad-hoc mesh-oriented 
networking, which is very, very different (in context, purpose, etc).
if you pursue this, I expect you'll find that there's a huge cultural gap
between telco-oriented stuff like SMS, and "proper" networking (IP/TCP/etc).
