What do you think of setting up a new type of order using XCP that essentially lets anyone do a "kickstarter" style threshold-or-everyone-is-refunded asset sale order?

" I'm buying x TOKEN for y, but only once amount z is bought at the same time."

Those orders would accumulate and then excute all at once, as soon as the goal is reached. Optionally you could put a date your order expires, which is a personal "end of campaign" threshold for each person.

and it would only be possible with an XCP based instrument, so bitcoin would be out and XCP is suddenly the crowdfunding token because it can be escrowed

That would take all the trust off platforms like swarm and coinpowers, and be one of the first real uses of escrowing on the blockchain, and a damn good use for XCP - Bitcoin is the currency, and XCP is the crowdfunding/cryptofinance platform built on top.
