Just received the WiFly from SparkFun Electronics:
WiFly 802.11b Serial Module - Roving Networks
sku: WRL-08869
Description: The WiFly RN-111b module from Roving Networks is a complete ultra low power embedded TCP/IP solution. The device enables wireless connections to any legacy serial port and supports bi-directional RS-232 signaling at a rate of up to 232.4Kbps. Just attach WiFly to your device's RS232/EIA232 port, plug it in, and you're connected. The transmit range can be up to 330' (100m), depending upon environmental considerations.
Features:
* Uses industry standard 802.11b specifications and protocols
* Supports WEP and WPA2-PSK(AES) encryption
* Can be powered from multiple supply options: 4VDC – 12VDC unregulated, 3.3V regulated, or low power (2-3V ) battery source
* Fully pre-certified module with FCC ID and CE marks
* TCP sockets with incoming and outbound connect modes
* UDP connectionless and broadcast modes
* Virtual COM support via Tactical Client
* Low power consumption (40ma connected, 120ma TX, 12 micro amp sleep modes)
* Programmable timers and wake/trigger modes
* Three on board LEDs and PIO signals for connect status
* Simple local configuration via AT commands
* FTP over the air firmware upgrades
* Includes 1/4 wave wire antenna
On board pin holes are 0.8" spaced
Dimensions: 0.3x1x1.5" (25.4x38mm)

Comments
Is it just a WiFi serial port eliminator? Not belittling this very useful feature of course ... it's just hard to tell looking at the data sheet. Can you send an HTTP request with it? There is great detail about command mode and using the escape sequence "$$$" to get there, but I couldn't find much info on data mode. Please keep us up to date with your progress using this device.
Thanks.

Hmm ... looks like you have to do this sequence: "$$$", "set ip host <ip address>", "open", "exit", send data to host
Quite cumbersome .... JMH will follow up I'm sure.

How about it, OBC? Just another proof-of-concept to add to our toolkit.
