Me neither.  The real culprit that causes applications 
over ssh to fail is a router in the path blocking all ICMP 
packets, I believe, rather than the small MTU setting
itself, although I haven't finally proved this.  Changing 
the MTU value is a just a work-around rather than a fix.

It was fortunate the small MTU size was in a router I have
access to!
