As a DD and knowing me to use your packages you can do many things :o)
But, yes, an authority that assigns tags to software packages (the authority 
could be in Debian or in some grid community) will have some influence on 
what software is eligible on some cluster's specification. Exactly. Think of 
these installations as transient dynamic events that are associated with jobs 
seeking a cluster on the grid for its execution. For some clusters in the 
grid a software will be allowed to be installed on demand (because of the 
debtags assignments to the software and constraints imposed by the cluster) 
and on others not.

Fine, but the now pending discussion on if it should be in or not we could 
have more easily within the Debian-Med than with Debian at large.

I see.

Fine. But we need a way for us to assign the packages then to tags that are 
not yet part of debtags. Or am I mixing things up here?

Many greetings
