python-egenix-mxuid 3.1.3-4.1ubuntu1 (amd64 binary) in ubuntu oneiric

 mxUID provides a fast mechanism for generating universal
 identification strings (UIDs) with intention of making these UIDs
 unique with high probability in order to serve as object or data set
 identifiers.
 .
 A typical use lies in generating session IDs. Other areas where
 unique IDs play an important role are RPC-implementations, ORBs, user
 identification, message passing systems, object databases, etc.
