Hmm, I've tried this a few different ways, and I haven't been able to 
get it to work the way it should. Maybe I'm just missing something?

Attached is a minimal test case I've extracted to show the issue I'm 
having. It seems the problem is that, while I can update the path in 
'eshell-set-path' with no problem, when I call 'eshell-get-path' again, 
'hack-connection-local-variables-apply' resets 'eshell-path-env-list' to 
nil, so the modified path is lost.

Do you have any ideas about what I'm doing wrong? Or maybe 
connection-local variables aren't supposed to be used this way. All the 
documentation I see on them involves setting variables to constant 
values, not updating them in-place over the life of a program.
