Absolutely. However I'm less well versed in international privacy laws than those of the UK. With RIPA, the mere act of protecting your data while transiting through the UK can be seen as incriminatory, with failure to decrypt data a serious criminal offence which can result in prison time.
I think that steganography and plausible deniability are vital. However employing such techniques can make life even more difficult if caught ("What are you going to such an effort to hide?").
There is a good solution: don't bring your data. It is a problem if the place you are going doesn't have broadband, but then again there may be little work that can be done in such a place.
I don't know if I'd say that's a good solution. If travelling for pleasure, that would mean wiping my personal data from my device - contacts, messages, emails. It would also mean logging out of all network services. Or just leaving that data at home. Being able to stay in touch while away, and retain access to my online accounts is really useful.
If travelling for business (even to a country with poor broadband access) I may still need access to vital business data. I can't always leave this at home.
Sure, I could VPN home but if I am to travel with no private data at all then that would preclude the possibility of using certificate based encryption and relying on less secure (and memorisable) passwords.
Travelling without data is very difficult today, unless you plan on being completely disconnected.
