Yes, but if we replace the current contact group implementation with  
tags, we won't be able to add contacts from one source to a group  
within another without some trickery with the tags - like appending  
the source key to the tag. Again, unless I'm missing something which  
is entirely possible. :)

The other concern isn't so much contacts from different sources but  
knowing exactly which groups/tags a particular source contains. My  
thought process is: Individual contacts are tagged, placing them in a  
"group".  When you browse an individual address book source, to know  
what "groups" to display in that source we would need an additional  
query to the tag table/backend to find out which contacts in the  
current address book are tagged with what.

Another thought, what would happen if you have PERMS_READ on a source,  
but want to include a contact from that source in one of your groups?   
You would need to tag that contact, but don't have access to. Another  
issue is how to deal with sources that multiple people have PERMS_EDIT  
on. Tags would have to be per user, since I may not want a contact in  
the same group that someone else with access to that contact does.   
Again, just my observations, and I may be missing something here..
