AFAIK, a lot of servents use the file name and the file size to determine if one file is the same as another. However, some servents may have adopted the HUGE proposal (Hash/URN Gnutella Extensions) which proposes that a SHA1 hash for each file be used to determine exact matches regardless of file name. The hash can then be used within queries and query hits in order to find a specific file.
