I definitely agree here personally.  Clients could connect to this 
"proxy" and subscribe to only the events that are interesting or applicable.

I've been considering writing something like this for a project that I'm 
thinking about doing that would require potentially high number of 
concurrent clients to consume AMI services.

 From your experience, does the software that you wrote require 
significant CPU to cache and then doll out the kind of volume of 
messages that AMI can send?

If I end up writing something myself, I'll release it as OS...
