James,
I took the remap route and all is sweet at the moment. The place that did my tuning, as you know, are able to do pretty much anything with the ecu, except for the features as you mentioned. They can also do a few other really cool things with the ecu as well. Bit hard to explain on here but they can put on "Valet" mode etc. Stops dickheads thrashing your car basically.
A whole lot cheaper than a Link I'd imagine.
