I am particularly excited about making intel-compatible hybrid CL  
applications were MCL specific functionality like UI runs under  
Rosetta while the rest executes on an intel-native lisp like CCL.  
This provides a smooth transition path from MCL to native intel CL,  
with the application initially running mostly under RMCL but over  
time incrementally ported to intel native lisp. MCL itself could be  
ported to intel that way.
