You could also use BER encoding (as in perl's pack("w")):
Its bytes represent an unsigned integer in base 128,
most significant digit first, with as few digits as possible. Bit
eight (the high bit) is set on each byte except the last.
With this scheme a 1 byte length can encode a length of 127, a 2 byte
length can encode a length of 2^14-1 (16k), 3 bytes encode a length of
2^21-1 (2M) and so on ...
