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.

Number 2 is the ethernet port.
On the left is an Ethernet port and the right a Modem/Telephone port.
In order to connect with one wire you need to use a Cross-Over cables and set IP addresses in the same range for both devices! 192.168.x.x; 10.0.0.x .. etc. (or set your mac as a DHCP server)
If you don't want to use the cross over system then you will need a router that has a DHCP server and assigns IP's to each device automatically. And then check the Router on its ARP table what the IP of your Arduino Ether shield is for communication.
If you have a newer airport then you can plug the Arduino Ethersield into any one of the free ports on the Right Side
If you have an old airport then you will need to get a switch and remove the Blue cable form your Imac. and plug it into the switch. Then get 2 new cables and connect your iMac to the switch and the Arduino EtherShield to your Switch.
Here are some setup examples
I am not sure if there is a single chip avaialbe to do this, but you can have a look a few examples..
The arduino can be be programmed very easily and all the tools, code and IDE is free and open source. This not the only available one and there are several different architectures that benefit from their own subset of features,pros and cons. Building a simple internet bassed arduino wont cost you too much. But this is not recommended if you want to go mass production though.

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.
