[LAU] Why telnet for communication between applications?

[Crypto]

Hi,

reading recent posts concerning telnet there is one thing I have not yet 
understood:

Why would I use telnet for interprocess communication rather than e.g. 
transmitting commands between two applications via software MIDI ports ?

Is it (much) faster? Or do I get less protocol overhead, or...?

Thanks for shading some light on this,
Crypto.
