In theory this is true, but if you use any transport that does not
provide message boundaries, you need close integration of the data
receiving code and the actual parsing of the OSC message. This is
because you don't know where in a stream of bytes for a message
ends until you have at least parsed the path and the format string.
So you can't just 'wait for a message' without interpreting it and
then only when it is complete pass it to a decoder.

If the transport is just a stream of bytes, you *could* wait
until no more data is received for some time and assume that the
message is then complete, and pass it to a decoder. This will of
course introduce delay, and it could easily fail.

Now UDP is the only common transport that *does* provide message
boundaries, so probably that's why it is said that you need UDP.

True.

True, sort of.
