According to Paracel, their version of Blast does exactly that: it 
fragments both the query sequence and the database, and the output -- 
including P and E values -- is identical to the output of NCBI Blast 
applied to the entire (non-fragmented) query sequence against the 
entire (non-fragmented) database.
