Sure, it is feasible. I don't know any book. There are some RFC (1057 and
1014) on the RPC protocol as implemeted by Sun. Your mixed environment
does not constitute a problem (you can find Sun RPC in any
of the platforms you indicated).

I have IBM TCP/IP for OS/2 Toolkit. It contains the Sun RPC programming
tools and libraries and also Apollo's NCS (Network Computing System).
There are also RPC implementations not based on TPC/IP: for instance
Netwise RPC which can also run over SNA and connect IBM mainframes.

No problem. Clients can run both protocols at the same time. If you 
want to implement RPC on the Netware server there is a Novell product
called Netware RPC (but I think it is not compatible with others RPC
implementations).
