Hi,

I would like to understand the problem here, before I start to discuss 
potential solutions. You seem to be saying that there is some kind of 
card<->component connection limitation? Is there specific use case you 
have in mind?

Personally I don't see a reason for connecting component to multiple 
cards. Even if it would be possible it soon becomes problematic when you 
for example try to decide which card controls clock on component. As 
I've wrote I would like to first see some use case definition, before 
jumping into a rewrite.

Best regards,
