I have read up about that Ruf-bot project amongst other things.. However where the modules I have are different to others I have read about, is that they are a transceiver. Can transmit and receive with the one module. They also had the TWS/RWS modules, however I wanted 2-way data, so for the price of 2 transmit, and 2 receive modules, I could get just 2 transceivers and save my pennies.

If I ditch this idea, and go for 2 transmitter, and 2 receivers, can one of each be connected to each 16f877 in order to give me bi-direction data? If so how does that work? both connected to the same serial pin, and either module 'selected' as it is needed?

I've hit a wall with the datasheet, it's got many many pages of registers that it looks like I need to set before I even think about sending data.
