Yes, I think spawning a shell is the difference though manually
backgrounding it in my test script worked ok, just took me a few minutes
to figure out what was going on since I didn't think backgrounding was
necessary.
I was killing the port 9000 sexpect process and then respawning it at
the top of the loop as an ugly way of clearing the buffer.

No, index 0 is the currently playing song if you use the dash in the
query - from the cli page:
Code:
--------------------
Set the parameter to "-" to get the playlist data starting from the current
song.

The busybox wget doesn't do post. Haha, I know, get a different version
that does, and any sane person would, but I seem to be irrationally hung
up on not wanting to bring in extra tools, even though I have to for some
things.
Just a few minutes ago I finally figured out how to get the json data just
using the busybox nc, that was driving me crazy. I couldn't understand
why it was just exiting without returning anything. It's the sleep .1
that made all the difference.
Here's the little test script I used:
Code:
--------------------
#!/bin/sh
post=$(cat <<'END_HEREDOC'
POST /jsonrpc.js HTTP/1.1
HOST: 192.168.1.201:9000
Content-Type: application/json; charset=utf-8
Content-Length: 97
{"id":1,"method":"slim.request","params":["b8:27:eb:94:ae:63",["status","-","1","tags:acgltys"]]}
END_HEREDOC
)
(echo -e "$post"; sleep .1) | nc 192.168.1.201 9000 | tail --line=+7 > json.txt
--------------------
So now I'm thinking about trying the log watching method so I can detect
newsong events and retrieve the json with just busybox builtins.
