9p is quite useful. But the same semantics could've been implemented using a more universal but compact structured format such as s-expr. It is not the only choice but to me it seems to strike a reasonable balance (compared to bloaty XML at one extreme, tightly packed binary structures at another, and byte streams with printf/parse encode/decode at the third extreme).
