I had to modify the mod_jrun22 apache connector in order to get this to work. I am now able to have individual virtual sites bound to specific instances of CF while still having session replication working.
I spoke to someone from macromedia and he told me that this should indeed be possible and several large companies are doing this. He wasn't sure, however, whether it would require a custom connector. I emailed him a while ago but haven't heard back.
