Questions:

1. Is it be possible to create a second partition on the USB drive in order to store any install files and such? I'm imagining that partition 0 has the bootable Ubuntu Live environment and partition 1 has bitcoin install file, truecrypt install file, etc. This is so that you do not need to redownload the install files every time you want to use the wallet.

2. Do I need to wait for the blockchain to download every time I want to send coins from my savings wallet? Or if a partitioning scheme like I mentioned in 1. above works, could I somehow keep the downloaded blockchain stored in another partition and only need to update it when I boot Ubuntu? If that is possible, how would I do that?

3. Let us say I boot Ubuntu from my USB drive, install bitcoin and such, then mount a truecrypt container with my savings wallet inside. Do I then copy the wallet.dat into ~/.bitcoin to use it, or should I make a link (using "mklink" as discussed above) to the file inside the mounted truecrypt container? (I don't actually know how links like that work, so this question might not even make sense.)

Thanks to anyone who can answer my questions. I know how to do the Ubuntu Live install and all that, but I want to make sure I know how to juggle all the other files and things I will need.
