thanks -- I played around with a few of the formats and 
read the docs, but what
I'm looking for is someone to tell me that it 
really does work and if I spend
the required time to figure it out it will 
be able handle millions of entries.
(I read a couple of posts on various bulletin 
boards that seemed to suggest that
I'm pushing the envelope here.)
