Difficulty is not only influenced by price. If ASIC hots BTC then there will be a lot of GPU miners who cant make anything mining BTC and will be likely to switch to LTC. This will make difficulty skyrocket but may not have any impact on price!
Take a look at Pyramining. Fnds invested in mining hardware and earn a guarenteed minimum 10% on original investment. Links in Sig take you to the site hich explains the system in detail.
If LTC is going to become silver to BTC gold, then I think it would be useful to be able to see all holdings on a single display. No One has yet coded a wallet that displays your BTC and LTC holdings togtehr in the same place. I think this would be useful and if it is a good wallet, will encourage people to look into LTC.
You will need to be quick to execute a sucessful double spend. Once it is obvious this has happened, confidence in BTC will plummet and any BTC that you have double spent will become worthless.
I use armory but I also have a long passphrase to unlock my wallet. This is stored in password safe, which I use to manage all of my passwords. Very useful. You can also encrypt your wallet using truecrypt but if you are using it regularly you may want to prioritise easy of access over security.
I would agree that it looks as though he is developing (or at least involved with developing) some form of ASIC himself. I would not want to pre order anything at this stage from any of the companies as they have so far proved nothing and w ehave no idea when delivery might be (apart from a vauge indication from BFL - but with no actual product this may well slip).
I am happy with the current situation. If we start to get left behind, Pyramining may need to look at buying in some ASIC hardware from existing manufacturers.
