I have my USB set up to boot backtrack w/ persistent changes. Is it possible to encrypt the USBs files and still be able to boot from it without causing problems?
and if not that... is there a method I can use to make my USB's contents more secure and still retain all of it's functionality?
Or at least make it appear to be more benign than it is when you plug it in to a computer.
any ideas?

Failure to do so will probably get your threads deleted or worse.
Lock it up in a sturdy container when not in use.
Seriously though, can you tell us exactly what you're trying to secure your Backtrack install against? Storage based encryption is normally used to protect the confidentiality of data in the event that the storage device falls into the wrong hands. Are you concerned that people finding your USB stick will know you are using BackTrack?

Trucrypt is exactly what you want, but i see no need to follow the guide here as the one on there site explains much much more and you'll get a better understanding of whats going on .... Unless there is some special configuration you must do to make it work with BT and i dont think thats the case.
You could even have it set so you enter one password to boot ubuntu and the other to boot BT that way if someone asks you what is there you can show them.
cheers
Using backtrack for the first time is like being 10 years old again with the keys to a Ferrari.

Of course, if you really wanted to have some fun, go to Wal-Mart late at night and ask the greeter if they could help you find trashbags, roll of carpet, rope, quicklime, clorox and a shovel. See if they give you any strange looks. --Streaker69
If he is worried about physical access, he could use a Bio USB stick (requires a fingerprint to access). I've used one for about 4 years now without any trouble at all.

It's a BioStick and I've never had a bit of trouble with it. But, I don't boot an O/S off of it either. My Laptop (lenovo SL400) has the same thing, and so far, it has worked everytime too.
