I stumbled across a little Huawei sim called eNSP, that theoretically can be integrated into GNS3 via Virtualbox (Supposedly Amiga forever can too, but i'm not doing that either).
Has anyone ever used this? Good, bad, indifferent? It's supposedly similar with Cisco's Packet Tracer, but that's lacking in and of itself. That's why I stick to real hardware or GNS3.
