[rt-users] Can two unique instances of RT share the same database?

Thanks Seph.  Just to clarify my two unique installations of RT using a 
shared database are installed and fully operational.  I've already confirmed 
this appears to work fine on the surface.  I just want to make sure there 
aren't any known gotchas with a configuration of this type.  I forgot about 
the mailgateway and command line clients essentially doing the same thing so 
it sounds like everything should be fine.  I presume RT must have some type 
of table locking to prevent database corruption from multiple users with 
even just one instance of RT.  I'm just hoping this applies to two instances 
of RT as well.
