Oh, and then you must figure out either a length system for each part of the
string, or sentinels and delimeters for the ends of strings. Then you must
figure out how to escape the delimiters if your users type them inside
strings. Then you might need a system to name each data element.

Oh, and then you might localize, and need to pack UTF-8 into your strings.

Use XML. If HTTP is slow, even to a server you programmed, then rewrite a
simpler version of it.
