Hiyah, I'm new here

I've been looking into the possibility of having a chip running a very small web server, talking directly to a serial port.

I've had a look around at some of the different chips I might be able to use. I've used PICAXE chips in BASIC in the past, but all of this is basically new to me.

Can any one suggest a good chip which is easy to program, includes a TCP stack and can talk to one or more serial ports?

I might need to manufacture them in bulk at some point in the future... Anyone any ideas?

Thanks in advanced
