FTPmicro is a web-server or ftp-client, as big as a DIP40 package, based on the PIC18F67J60.
Despite the small dimensions, the board has some interesting features:
1) A microSD card slot
2) A TC1047 temperature sensor
3) Many analog and digital I/O pins
4) Microchip TCP/IP stack
5) Connector for the ICD2 programmer/debugger by Microchip
