I think I misunderstood this when you asked it.  You mean let the Layer 
have a hand in looking up the service?  I'm not clear if that's you mean 
by "resolve the concrete service implementation" though.

If the Layer of the module of the class calling the 
newInstance/newFactory/etc. method could somehow be consulted in service 
resolution decisions, that would definitely solve the problem because 
our container Layers could refer to the default implementation we 
provide, unless the TCCL overrides it.  This would in fact be an ideal 
solution since we could throw away this horrible proxy layer.
