[Opensim-dev] external host name

[Cristina Videira Lopes]

The thing is that this can potentially create a RegionInfo data 
structure with
           nRegionInfo.ExternalHostName = regionData.IPADDR;

This is inconsistent with certain queries on the Grid server, like "give 
me all my neighbors" which may send host names.

So, back to the point: someone needs to decide what is it that 
RegionInfo.ExternalHostName  is supposed to hold.
