	Ok, let me rephrase that question: in your opinion, how
*expensive* would it be to instantiate two SA objects? I went ahead
and hacked this into mimedefang.pl -- essentially, I just copied
spam_assassin_init to spam_assassin_net_init, gave
spam_assassin_status another object, and had it call the new object
conditionally on the value of a new global variable that I'm switching
in filter_begin, just before calling spam_assassin_check. (I realized
belatedly that just because filter_relay is where one first has access
to the relay IP doesn't mean it's the place I want to do my
checking...)
