I think that the least amount of typing you will get by using the 
cassette port.

The minimal size of a loader program from the cassette port is 192+2 
bytes. That is what the auto-starting loader of my c2nload is using: 
load the program as part of the compulsory 192-byte tape header, and 
then load 2 bytes that cause a jump to the tape buffer.

Maybe the C2N232 could be replaced with something dumber, using the 
audio output of a computer, tablet or smartphone. It could be somewhat 
of a challenge to implement bidirectional transfer. If the interface 
were to play nice (and emulate the loading of tapes), then it would have 
to connect not only CASS READ but also CASS SENSE and CASS MOTOR. With 
that you would already have exhausted the 2 outputs and 1 input that are 
available in a TRRS connector (stereo headphones and microphone).  
Something magical would be needed to additionally connect CASS WRITE.
