While I don't think that the use of the SEL should be restricted as Bert
has suggested, the ATM switch already has to be able to keep track of 
multiple ESIs per endsystem.  ILMI allows an endsystem to register any 
number of ESIs  (generally limited by implementation).  So, using multiple 
ESIs doesn't place any new requirements on the switches.  However, not
using the SEL byte does reduce the potential number of ATM services
that can be addressed on an end system by a factor of 256.

FWIW, all switches I've used have allowed each host to register at least
eight ESIs per port (and some at least 32).  Digital's UNIX implementation
of ATM typically registers nine ESIs per NIC with a switch, and so far
we haven't run into any switches that can't handle this.
