Question on loopback interface

Hi,
   In the lab, on routers which perform redistribution between multiple
protocols, do we have any rule of thumb where the loopback interfaces will
be originated from ? The reason i am asking is, this can have some
consequences in later stages like multicast, etc. Just wanted to know what
is the best practice.
   I dont think the proctor can help here as it depends on our perspective
of the given scenario. Any pointers are appreciated.

Regards,
Vamsi
