I am thinking about starting a project and was just looking for some general input. Where I work our company currently have remote stations that take data in from a radio link and input the data to a sql database. I am responsible for maintaining the stations and their scripts. Currently they are just running on a desktop pc connected to a radio receiver and an internet connection. I have had some limited experience with working with embedded systems in the past, and would like to explore the possibility of migrating the current setup to an embedded system. The most difficult aspect of the project that I can foresee is gaining internet connectivity to a pic chip and having enough memory for the libraries that would be needed to connect to a sql database. Can anyone recommend a resource so I can learn how to connect a pic chip to the internet as well as any recommendation on what kind of pic chip to use? I know this can be quite a daunting task, but I like to think that I am up for the challenge.

Some members of the PIC32 family, such as the PIC32MX675F256H and PIC32MX795F512L include an integrated Ethernet interface. An evaluation board for the PIC32MX795 is available: DM320004.
You can also add an Ethernet controller and use Microchip's free TCP/IP stack with their PIC18, PIC24, dsPIC and PIC32 families.
