It is either that, or grab http://secondlife.com/apps/mapapi/ and parse 
the second to last line to get an up to date, complete database of 
handle to name mappings (and vice versa) that removes the need for all 
of the other steps. In an ideal world the Lindens would implement every 
new packet we think of, but I've requested at least a half dozen over 
the last year and have slowly become fond of finding ways to make things 
work without changing the grid backend.
