ASM - remote access via listener and sql

We are trying to write some monitoring tools to check the health of ASM-
in doing a routine install of RAC using ASM on IBM AIX, I find that no
listener / tnsnames config is done for the ASM instance.

 

Can ASM be accessed remotely ? Is there any surprises (other than
reduced views) in doing this ? Is it supported ?  Thanks in advance.
