Here is documentation on how to get Bitlash up and running on various hardware combinations.
Bitlash 0.9 includes working support for the AdaFruit Ethernet Shield with Lantronix XPort Direct. The configuration is set up to allow you to telnet in to your Arduino and control it with Bitlash. The quick summary:
Make sure your Xport Direct is set up like this:
*** Channel 1 Baudrate 9600, I/F Mode 4C, Flow 00 Port 10001 Connect Mode : D4 Send '+++' in Modem Mode enabled Show IP addr after 'RING' enabled Auto increment source port disabled Remote IP Adr: --- none ---, Port 00000 Disconn Mode : 00 Flush Mode : 00
This configuration sets up for incoming telnet on port 10001. If you would prefer a different port, configure it in the “port” parameter of Channel 1.
Use your favorite Telnet program to connect, and off you go.
One little thing. You MUST use “mode character” in the telnet program. If you don't, you'll see garbage as the XPort swamps the Arduino with a whole line of data at a time.

Now you are connected to Bitlash on your Arduino over the internet. Anything you used to do locally with Bitlash, you can now do from anywhere.
The same serial io interface used for the AdaFruit/Lantronix XPort Direct should work with suitable adjustments on other network adapters as well. The reader is encouraged to experiment and report back with interesting findings.
We've got Bitlash 0.9 working with the AdaFruit preprogrammed Atmega328 chip for twice the PROGMEM flash and twice the EEPROM space. Bitlash 0.9 automatically detects the '328 and does the right thing at compile time to use the extra space. http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1226117225/2
These instructions from extremis on the Arduino board were very helpful in setting up the Arduino environment for the '328, but be prepared for a little experimentation since it's all still pre-production.
It does not appear that this '328 bootloader sets pinMode(13,OUTPUT) like the Arduino stock bootloader does. So set pinmode(13,1) yourself if you want to use the debug LED.
The Sanguino is an awesome big brother to Arduino. It's based on the ATMega644 with 4x the EEPROM and flash. Preliminary Bitlash support is up and running in 0.9 with the Sanguino 1.3 software - including proper setup and use of the two hardware UART channels and the bigger EEPROM data store. Be aware there are serial port issues that require a patch so please ping for details if you have a Sanguino. Here are some notes from the port:
