With the Kickstarter project, will we require USD or can we do LTC?
Most crowdfunding platforms allow whatever fiat currency you use to convert to USD. The reasoning for why we need to do this at present is outlined in post
#902. I do foresee that this will change one day, but right now we don't have cryptocurrency platforms to do so, as we need to bridge the space between funding to development. It may be an extra step for a few people, which sucks, but in the bigger picture it's no big deal.
Actually treating and following this subject in the btc community forum and keeping people attended and informed about this new cryptocurrency that is coming to change their experience of using previous ones, but then limiting the already established fan club by a fiat payment only, not only sucks but hurts and disappoints as well

That is true, things are not ideal, but I think creating a btc exchange account (in Bitstamp, MtGox..) and letting the btc users to pay and buy limited number of tickets through it, based on the current exchange rate of usd/btc at the moment of payment, wouldn't hurt anybody. This can at least be done for small investment/purchase of the tickets (<1 btc~=$100 for example).
The final amount received in that account (after reaching a cap perhaps), which will be in $, can be easily transferred by the use of wire system to any bank in US and Europe in not more than a week (you can include and charge the transfer and other fees this method may cause, to the investor's payment bill)
It will be wise to let 30% or even a bit more share of tickets to be sold this way (and you may put a limit for each purchase, by using btctalk id, to avoid rush or unfair distribution). Your currency will certainly have a brighter future if you let more people in to have a piece of the pie (even a very small one).
It's bad enough that those paying will have to provide identifiable information, but it's even worse if they have to connect it to their Bitcointalk ID too. That reduces security for the participants in exchange for decentralization of power. I think in this case security is more important than decentralization of power because power can be decentralized in other ways and at later times. Honestly, the people who buy in early aren't really guaranteed a larger piece of the pie than people who buy in late, they aren't necessarily going to have more coins, it just means they believed in the project from the start and were the first to become stakeholders and take the plunge.
