We do this one;  it's been working well for years.  The only downside, 
in my view, is the network traffic pushing all that mail back and forth 
to the scanning server.

We also switched from randomly picking a configuration file (each one 
set up for a different clamd node), to using Linux LVM load balancing a 
while back as well.  We originally hit a "Damn Thing Don't Work" error 
trying that, about half a dozen Clam releases and about for Debian 
releases ago.  I don't recall ever seeing an actual cause we could point 
to, and IIRC as of the server refresh we did for our current systems, it 
Just Worked.
