There's currently no way to have mimedefang use spamc/spamd.  
However, mimedefang is written (mostly) in Perl, and makes use of the 
Mail::SpamAssassin Perl module rather than calling a separate 
instance of spamassassin.  Additionally, the mimedefang-multiplexor 
pre-loads a number of mimedefang processes which handle simultaneous 
messages in a fairly efficient manner.  This also eliminates the 
resource impact of starting a new Perl process for every incoming 
message.

When writing your mimedefang-filter, you should probably set up a 
size check on e-mail prior to SA processing.  Most spam isn't very 
large, so you can safely bypass SA checking for messages over 50K or 
so.

What kind of hardware do you have, and how much mail traffic do you 
see?  You may find that even quite modest resources are sufficient to 
handle both MIMEDefang and SpamAssassin, depending on load.
