Agreed.

Agreed. This is what we discussed conceptually last week at the DevCon. 
I just don't understand why Realtime was supposed to 'save memory' at 
all; Asterisk servers don't generally use a lot of memory. I think the 
real motivation for reducing the number of peers in memory was NOT 
memory savings, but instead was to reduce list searching and lock 
contention, problems which can be solved in other ways without bringing 
in all the negative side effects of realtime loading and caching.
