Hi Stephen

I developed an Alert management system Ensemble based that you might find of interest.

It connects to the end user systems via Email ( it was intended to serve hospitals & they don't like web services as its  not protected enough, yet you can use any connection ) , the system reads the alerts process them & send them further for processing, I'll try to send you some screen shots.

Simcha

ps my email is shiluvg@gmail.com if you are interested

pps I tried to upload the screen shots with no success if you'll send me your email I'll be able to send you the files
