either way - it does comunicate with Catalyst in the 2.x.x.x artnet range, straight out the back of the desk. (and its easier programming on an MA!)

S
a console can send to many simultaneous addresses in any ip address range.
it can only receive if the address to be received from is the address of the console or a broadcast address.

receiving from different addresses simultaeously on the same computer is also possible - its called - multihoming. but is not so common - but may be being used.

there is also a mode that software can use - where it can receive every tcpip packet on the net without filtering at os level. this is called raw mode....

its all quite complex...
