Stew,
As the others have pointed out, transferring or E-mailing photos at net cafes is NOT a realistic option, for several reasons. While a Card Reader will allow you to transfer photos, the time to upload images (especially larger files) will be significant.
Having photos burned to DVD at local shops is certainly an option. Many people have two copies burned, keeping one with them and mailing the other home. That way there's some "insurance" in case something happens to one copy (always good to have a backup, especially after the memory card has been re-formatted!).
The most practical solutions would be to either take additional memory cards (memory is cheap now, so this shouldn't be cost prohibitive) or take a portable storage device (Portable hard drive). You didn't specify which Camera you have, but I'm assuming the file sizes aren't too large?
You might want to check www.adrianwarren.com ("On The Road" section) for a good overview of storage methods.
Happy travels!
