You could go raw TCP (you don't need full telnet). Instead of ssh, allow 
binding the TCP port to a specific interface, so the user can bind to 
127.0.0.1, and then you can use a regular ssh client to tunnel to it. Also 
consider a Unix socket (or for Win32, a named pipe).

Both of these give you a raw byte stream over which you can send a simple 
command stream.

Depends on how fancy you get. You don't have to implement a fancy graphical 
system. Unreal Tournament (the game) has a pretty nice web admin interface 
that's not that big a chunk of code. Embedded web servers can be pretty 
tiny. The hardest part is probably the URL parser, and if you've already 
got to write a command parser, you're most of the way there.
