I was trying to say that in each case one should think about the pros
and cons of different approaches and be wary of dogmatic rules.
I wasn't recommending the use of sequences in your case. I would
actually be surprised if they work well for you.
But having said that - by all means try it. Maybe it does work, and
you'll give a talk about "The 50 million sequences database" at a
conference next year :-). Or maybe it doesn't, and then you'll have
learned something about where the actual limits are.
