SQLNS v2.0 can probably handle what you're describing, but I don't
think it's going necessarily be a trivial development process. You'll
need to create custom event providers & custom delivery channels. 

Do you have the option of upgrading to SQL Server 2005? If so, check
out Query Notifications as a possible solution. I think it's probably
a better technological fit for what you're trying to accomplish.

If you're constrained to SQL Server 2000 and want to pursue the SQLNS
route, keep posting questions/comment/etc.
