You can construct a boost::function at the call site explicitly

Alternately you can provide an overload of Subscribe for function pointers.

That kind of defeats the purpose. I'm trying to make Subscribe figure out the type of the packet itself to avoid having to explicitly say "I'm subscribing for a WalkPacket" when the signature of the slot already has this information. The current implementation requires this syntax:

Subscribe<WalkPacket>( &walkPacketCallback );

If you only need to deal with function pointers,

template<class T> void Subscribe(void (*callback)(const packet_t&)) { Subscribe(boost::function(callback)); }

What about for function objects?
