GFT are the only true spreadbeting company I've come across who have an API. They're a bit protective of it, I think mainly because they worried about being arbed by scalpers. They seemed quite happy when I talked to them about using it for LTTF-style trades. I never got around to taking it further than initial enquiries, but only because I found I was moving to the US for a while.

Take a look at WorldSpreads. For many contracts you can set a stop based upon the market price, not their price. Which makes the spreadbet stops match the futures stops much better. They don't offer it for everything, but mostly it's the most liquid, tightly-spread markets that are missing, so it's not such a problem. In theory they have the option of hitting you with substantial slippage on the price you actually trade at, but in practice they seemed to operate fairly.
Two slight oddities with Worldspreads. Firstly the stops only operate while they're in the office - from about 7AM London time to NY futures close. That feature I found produced a generally positive effect, because it omitted the occasional wild swings in the thin overnight markets. Secondly, they always make markets on a fixed spread around the market mid price, so occasionally, for example in the less liquid US futures during the London morning, their bid-ask price is actually inside that of the actual market.
