TCP is a stream with no packet boundaries. If you want to separate that stream into a series of messages then you need to do packetisation. The SLIP delimiter approach is a pretty good one. You're right that it was originally for segmenting a serial link to send separate IP packets (so you could theoretically have SLIP over TCP over IP over SLIP), but it works just as well in other contexts.
