[HECnet] SIMH experience?

I used to run my GRE tunnels over both real and emulated Cisco routers, until I discovered Paul's PyDECnet and it was a drop in replacement for my Cisco. It's probably the simplest way to get connectivity running. I've setup my office machine which is GRE connected upstream into HECnet and a secondary GRE connection to my home where I have another host. DECnet works exactly as I would expect. I know we've all said it before, but kudos again to Paul for one of the most useful pieces of networking code. With DECnet support being deprecated everywhere (including a broken Linux kernel implementation), it was refreshing to see something current and working on modern boxes. Cheers, Wiz!!
