EDS only uses one byte per character for strings
(except for extremely rare cases where 2 bytes might be used). 
There's also a couple of bytes of overhead.

I'll think about it.

The data is already slightly encrypted,
i.e. you can't load a .edb file into an editor
and visually read the strings or the numbers.

I'm not sure I want to implement one of the
strong encryption algorithms. There are still some
U.S. export restrictions on encryption algorithms.
I wouldn't want Euphoria to be banned from
distribution by the large U.S. shareware sites.
