I'd like to see him merge his project with Marco's . If so then I'd be 
more than happy
to see this stuff come in once it reaches a certain level of maturity.

Marco and I have been going over some possible macros that could be used 
to help with
a lot of this and if the macros were used then some of the changes could 
come in quite early
as they would compile out to NOPs for anyone not using the changes.
( and provide an easy target for removal if it eventually doesn't complete).
