I'm reading through the wiki page on Contracts (https://en.bitcoin.it/wiki/Contracts) and am trying to understand exactly where in the transaction the various SIGHASH flags are placed and how they interact with the inputs/outputs. By reading the page on OP_CHECKSIG (https://en.bitcoin.it/wiki/OP_CHECKSIG) I still can't quite visualize what a transaction with these flags would actually look like. Does anyone know where I can find an example of one of these multi-sig transactions? Ideally, the format used for the basic transactions page (https://en.bitcoin.it/wiki/Transactions) would be great, but just seeing a plaintext example of one of these transactions would be really helpful.

Thanks guys. I think that what seems to be happening is that on my Mac (running Mountain Lion), whenever the screen locks from inactivity, the syncing process stops actually downloading/processing new blocks. I then have to shut down and restart Bitcoin-Qt in order for it to start up again.

I've been trying to fully sync my (standard) client for weeks. My blk0001.dat and blk0002.dat are up to about 3.4GB total, and I'm about 98% synchronized. Is the multiple week timeframe typical or do I have something configured incorrectly?

Does anyone have thoughts on whether the same legal issues BitMit ran into in Hong Kong would also apply in the U.S.? Does it make any sense for U.S. citizens to attempt to purchase BitMit? I haven't seen this discussed on other threads, though I may have missed it.
