Little Nix/BSD routers & WAN link emulation..
[..that you may or may not want to run in VMWare]
Having skimmed the wikipedia entry on network emulation someone pointed me to in a thread that's wandered off somewhere, they're either expensive which I don't want or care about (very rough approximations of slow links is fine) or suprisingly big e.g. want 1/2 GB RAM.
Apparently Linux kernel 2.6 has NetEm. So has anyone seen any little router/firewall distros that might have the right bits in it, but not the kitchen sink?
