Perhaps this could be all done with just 1x (INPUT), between consenting pairs:

C: gemini://.../specification.gmi?⇄gemini://.../delta.txt --notify the server of the location of the delta and to switch role to get it, as indicated by the ⇄ sigil
C⇄S: <start role reversal> -- the client maintain the network connection and accepts one gemini request
S: gemini://.../delta.txt -- the server request the content from the client 
C: 20 text/x-patch; length=4106 -- the client return the data to the server
C⇄S: <end role reversal> -- upon EOF
S: 30 gemini://.../specification.gmi -- client redirected to updated resource

This would require a persistent connection though. And some sort of indications of content EOF, be it length or otherwise.
