Holy smokes. I'm a lone developer, I can't afford that.
Has anyone tried the MySQL embedded DB yet? Michel RENON had brought it up,
I checked out the site, and it looked interesting.
Thanks for all the replies about this topic. I guess if the MySQL option
doesn't pan out, I might have to roll my own...
Thanks again.
