The macro ${dcc_userdir} provides that feature.
See the dccm man page.

Yes, you are right about that.  If any recipient of a message wants
greylisting, the entire message must be greylisted.  I do not understand
how running two dccm daemons would help that issue.

That is certainly possible.   However, please note that 

  the dccm binary is less than 700 KBytes, which seems like a small
    price to pay for an installation which can use the updatedcc
    script to install new versions.

  rcDCC invokes the script start-dccm, and start-dccm understands "-h XXX".
