Sorry to be spammy.  But.   [I guess I'm spammy today ;-)]


Since I am looking for a no-cache solution for james.
I've been looking into just doing a socks proxy against the static ip.

I will start up james, create a ProxySelector which does all ips except =
for 127.*/192.* and ssh proxy them directly via the
externally facing static ip aws instance.


Is there any red flag that goes off in your head for this?
