I used ebtables and packet labels/connection tracking to allow our in-house network VPN/Web servers to function seamlessly in our dual homed (but not BGP supported) internet connections, each with different public addresses and gateways. It's now stock functionality in VPN/Firewall appliances, we ended up with SonicWall, but at the time it nearly melted my brain. A second hardest was writing a cooperative multi-tasker for Turbo Pascal programs under MS-DOS.[1] It made a copy of the stack, and the first time it returned from spawn twice, I was really, really confused.... until it dawned on me that it was actually working as designed! There was a really weird requirement in an upload protocol I was using that required knowing how long the file was, before I was even done generating it, so I built a text piping engine to allow that to happen, and Tasker was part of that.
