Python application for embedded network device

I need an experienced python programmer for two small PC applications which interface to an raw TCP/IP socket. The socket is connected to an embedded device. The driver code (what to be send on TCP/IP) is the same for both applications. The protocol between PC and embedded device is well known.

The code must be platform independent as possible i.e. must run at least on Windows, Linux and MAC OS!

1) Simple (!) GUI Application: Showing some state (tracked changes from the embedded device via TCP/IP connection). Also allow TCP/IP and common settings via a settings dialog.

2) Simple Console Application: Emulate a virtual COM port, where another PC application may connect to (i.e. use a null modem emulator like tty0tty or com0com and simple connect to serial port). Emulate a (existing) serial device with well known commandset. Map the states of the embedded device (received via TCP/IP) to the serial device command set. Configuring the serial device is done via command line parameters.

Your solution must be:
1) Well documented (a manual is posted within our wiki)
2) Ready for install (egg) or especially for Windows as installer executable
3) Tested.
