A bag full of CF cards ??
The advantage is that you can 'spread them around'
Hide some in your hotel or give some to your buddy and keep some on your body - Im assuming theft is one risk
Internet cafe ? you could FTP images somewhere for backup or write CDs for your hotel room/buddy
CF cards are pretty hardy and very small - we put one throught the washing machine once
So if you fall in the water they have a higher probability of survival (esp if tied in a lubeless condom - ia have also seen condoms used for 'waterproofing' flash guns )
You could also backup with a film back - do they still sell film?
A truely heretic idea.. Save some space by shooting jpg high on a canon ?
I think you will end up with a laptop preferably with an external drive too to create a 'buddy' backup
With a lap top you could do some basic post and save jpgs that could be FTPd if you get net access - lets face it a half decent jpg is good for most applications
==============
For those considering a system - the internal memory of sinar backs , I believe, allows writing the content of the internal memory to CF cards giving the possibility of writing the same data to 2 CF cards for immediate deviceless backup
