You will need to supply a little more information
absolutely, and do remember the more you ask for (speed, peer to peer vs master slave etc) the more it will cost you in work and/or components. It is easy to say "I want a 1 Mbit peeer to peer network" and with the proper derivatives and a lot of software it is possible, but why encur the cost if a 115kbit master-slave will suffice.
