Yep, that kills it right there.

The current plan is a single machine  to store the files from the various head-ends on, keeping five days worth of each. The analysis will get done on other boxes and at this point isn't my problem.

I'm opting for  a pull mechanism from the server, I see a push from the clients as taking too much maint.
