Getting Taxonomy Lineage From Ncbi Gi Or Accession Number

Hey Guys

I have a specific question about getting a taxonomic lineage, given a NCBI accession or GI number. I have in the past used the module from CPAN (below) but I belv it only works for GI's and not NCBI Accession. Efecthing using NCBI etuils is not an option as we need to make millions of queries/weeks for blast results.

Bio::LITE::Taxonomy::NCBIlink

Just wondering if there are other ways to this with no dependency on fetching stuff from internet.
