I'm just thinking out loud here so this might be a stupid idea, but
if it's like VST, the plug-in just reads some "musical time info" 
at the start of each audio buffer and doesn't really care where 
that info has come from.  So how about having an array of tempo maps,
one of which (or more, or none) are the host's responsibility, but a
plug-in can also register itself as a tempo map provider.  Each 
plug-in gets read-only access to the tempo maps upstream from it.
Usually it will read the first one and ignore the rest.
