I think Genbank & EMBL sequences via WAIS, with keyword/author/accession/
species searching, makes a great deal of sense to the biology community.  
WAIS software seems to be well designed for the general task of indexing &
serving information, and the client programs are available for a
variety of platforms, and there is a ready advertising/distribution
scheme in the directory-of-servers.  It is pretty easy for non-programmers
to set up a WAIS server of any general text databank.

All that it would take to get EMBL & GenBank working well thru WAIS,
without an extra 300% disk space, is to modify the waisindex program
to teach it about the sequence file formats and how to index efficiently
without adding in all the sequence data.

I'm not volunteering for that task, but it looks like a fairly simple
programming job.
