While I don't actually know anything about the implementation details, my 
understanding was that DOSBox's "core=dynamic" option 
<http://www.dosbox.com/wiki/Configuration:CPU#core_.3D_simple_.7C_normal.7C_dynamic_.7C_auto>
 used the same "dynamic translation"  that you're talking about.

"dynamic The program instructions are, in blocks, translated to host processor 
instructions that execute directly. See also 
<http://en.wikipedia.org/wiki/Just-in-time_compilation>. In the most cases this 
approach is more efficent than interpretation, except for programs that employ 
massive self-modifying code. This option is not present on all host platforms."
