I'm actually using IPC::SysV to do the transport (some of the time). IPC::SysV can only move a certain amount of data per message (quite small, about 4k).

I've wrapped IPC::SysV in a module that sends data through and rebuilds it... thus the need for spotting the end of the message.

I was being coy about the transport because I'm also using TCP, and anything else that comes to hand...
