Right then, I think I have exercised all of the options I am willing to try myself. Blacksmith wasn't interested in heating it up, and his only suggestions were to keep tapping it with a hammer.
Armourtex have apparently never failed to remove a seatpost, as after trying solvents they stick the bike in the oven and use the heat to take it out. Prices there are pretty reasonable, especially if I combine it with a powder coating. Which seems like a good option, though it does rule out fadez. For now.
I have also contacted the forum's own coldharbour, aka Talbot Frameworks, and Oak, to see if either of them are up for the challenge. Then, the idea would be to rub boiled linseed over whatever was left over (hopefully an awesome scorch mark) and ride it around like that for a while.
