Agreed.  But a Transmeta "Code Morphing" layer for the CLR would make very
good sense.

Are you sure?  Last time I looked, .NET did *not* automatically cache the
JIT binaries between different invocations of the same program.
It would cache it between different invocations of a method, but it was
an in-memory cache that would only last as long as the process.

Please check your facts.
