Thanks, this was perfect. I have a good general knowledge of many  
different databases, but I have no specific tuning experience. This  
all made sense to me and I only needed to make the following changes:
query_cache_size = 64M
query_cache_limit = 4M
query_cache_type  = 1

I'll keep an eye on memory usage and performance and see if I need to  
make any other adjustments. I'd rather not witch over to InnoDB in  
case something changes in the future that makes it a bad choice (I  
don't want to have an unsupported configuration in such a situation).  
I did have MySQL running on a separate server for a little while so if  
this doesn't do the trick, I'll go back to to approach. I was trying  
to keep network latency at a minimum by moving MySQL back to the  
master backend. I guess there is no correct answer - just constant  
tweaking.  :)
