I'm so glad to be away from corporate IT and working with small teams of highly technical people where every request isn't "ok I'll fill out the paperwork" but "Hmm, we could do it like this: " We just created a small network, gapped from everything else, where you can just use the bandwidth but cannot possibly affect the production network. Since our bandwidth utilization is generally around 5% of maximum it's not issue to grab things using a 10Gb chunk of a few hundreds of Gb of bandwidth. The traffic is tagged with a low priority QOS packet so even in the worst case it will never affect network operation.
