Concurrency: yes, it can use the calling thread OR it can instantiate  
new thread that
will return the result when available to an callback interface. So  
anything is thread
save here.

Memory: Havent tested yet, because i think that parsing small XML  
files is also possible
on J2ME. "Could" be improved by implementing a Sax parser in J2ME. I  
have thought about
that but i think its kinda overpowered.

Query Handling: On J2ME it will use the "HTTPConnection" class to get  
an InputStream for
the XML parser. On J2SE it will use default URL.openInputStream().

API itself:
Some static reachable methods like:
NameFinder.searchAsync(String query, int maxResults, NameFinderCallback c)
NameFinder.search(String query, int maxResults)
will return an array of NameFinderResult Object which basically carry  
any data we have on
NameFinder: type, category, name, info, description, nested results...
