Distel

Well it's working now. Perhaps I was connected to the wrong node or  
something. I was seeing the message sent but not the return. I tried  
distel:who_calls(M,F,A) in the shell (which worked). Do the modules  
need to be compiled with debug_info? I'm also seeing it not work on  
all methods, I get response such as:

 >> REG_SEND: [TYPE erl-pid  185 0 0] rex [[TYPE  
erl-pid  185 0 0] [call distel rpc_entry (distel  
who_calls (couch_stats_aggregator get 1)) [TYPE erl-pid  
 1 0 0]]]
<< SEND: [TYPE erl-pid  185 0 0] [rex nil]

Anyway I suspect these are my issues and I can likely gets this  
worked out. Don't you love it, sometimes all one needs to do is ask  
one of the authors and it all starts working :)

Thanks much, it's a wonderful tool, I read the Gorrie paper on the  
design and I'm hopeful to spend more time with the internals as I can.

Regards,

Bob
