I've used TrueCrypt volumes with Dropbox before, and when I encountered a situation where I wanted to access the volume from two places, I took the sensitive data from Dropbox and just exposed it on my private network where I have more control over access. As far as I can tell, there isn't a great way to keep high security and flexibility when using sensitive data with Dropbox, but keeping sensitive data on the cloud is always a risky affair anyway.
