I've been asked to quote on several -

================
"PIC with an Ethernet interface and assignable IP address that runs
either a small web interface that when called will report the voltage
of a battery and the status of a switch. Ideally if it's possible to insert
some form of SNMP instead of a web interface but the main thing
is to be able to connect to the remote device and find out what the
voltage level is.

Also as an alternative and depending how difficult it is.

Same as above with at least 1 analogue input and 4 digital I/O"
================

The PIC part, easy as. The comms part though .....

What questions should I be asking ? The person who asked is right
into Wi-Fi, but whether that's the medium, I don't know yet

Is it possible to have a minimalist network interface (bit-bang ?) for
such a seemingly simple task ? I would most likely use an 18F1220,
up to 40MHz if required. 50MIPs Scenix is an option too
