It's, um, in my book.  ;)

We still use the RAP call (NetShareEnum) to request the list of shares.
WindowsNT/2Kx/XP use the RPC call (NetrShareEnum ... note the extra 'r').

The problem is that the RAP call can only handle 13-byte strings (one used 
for the terminator).  Names longer than 12 bytes are ignored on the server 
side when responding to the request.

The RPC call is harder to implement.

Urg.
