DMI freewire :
http://www.smartelectronix.com/~dmi/effects.html
a quite old plugin making your host rewired.
Not as good as a home-baked native handling of transport info & midi data (a midi -rearoute kinda thing), but maybe that it can do what you're after ?
I downloaded it ages ago, and never really found a use to it, so i don't really know if it works or not
