Looks like we need this, too...

On a separate topic, now that I've introduced myself appropriately, has
anyone written a SOCKS server which listens on the host and makes
ongoing connections through the lwip stack? We have the appropriate DNS
client support for that, don't we?

I'm writing a VPN client, but I don't want a normal VPN -- I don't want
to require root privs, and I don't want to set up 'standard' routing so
that any untrusted process on the box can connect to the private
network. I just want a SOCKS server which gives me selective access to
the VPN.

So although I'm currently just using the tun device and letting the host
route to my VPN, I plan to use lwip and SOCKS instead.
