I believe the latest release of Ensembl has ESTs mapped to it already. 
You could probably just mirror their MySQL database and use that
information to get the ESTs in a particular location.  You would need to
subselect for IMAGE clones, but that shouldn't be too hard (easy to say
when you don't have to do it!).
