[SR-Users] Is DMQ now the recommended way to do things?

[Canuck .]

Before DMQ there were other ways to do similar things.  Is DMQ now 
considered the best way? Assuming I am using recent stable?

Are there any good guides on clustering Kamailio?  I am not finding a 
lot of good info on that subject.  Specifically, for multi datacenter 
active active where things like floating IP's and keepalived are not 
really an option.
