Back of a Stamp

From ensembl-dev mailing list: advice on how to get the current list of all ensembl species:
List lives in the compara database and can be retrieved directly with something like:

mysql -u anonymous -h ensembldb.ensembl.org -P 5306 ensembl_compara_52 \
-e “SELECT name FROM genome_db”;

Or you can do essentially the same query via the Perl API:

use Bio::EnsEMBL::Registry;
my [...]

Problem:
Dataset 1: ChIPseq-derived transcription factor binding sites. Mouse. Mapped to nearest Ensembl Gene ID,
Dataset 2: Human Illumina Ref6 expression array data (GPL6097, I think) from various cell lines with varying amounts of said transcription factor.
Question:
What are the targets of the transcription factor doing in the expression datasets?
Quick Mapping
As a quick approximation, map the Illumina human [...]
