How about an application/bytes-at like this:

-- Starts with an 8-byte binary unsigned integer (network byte order) giving the position at which these data are to be written
-- the data follow

Makes you independent from intermediaries bashing headers.

(A potential application/append-bytes, without a position, would be bad, because part of your old PUT could still be in a TCP retransmission queue somewhere, creating a race condition.)
