Just to concur, that lwIP will run without an RTOS, meaning it will run with any RTOS just by keeping the code in a single task. The RTOS porting layer is quite simple too, so I can't imagine there will be any RTOSes that it won't work with. That said, personally I would not use it with an MSP430. I have done similar projects using external interface, like the WizNET parts, where you get TCP/IP on a dedicated chip with a simple I2C interface.
