Not currently.  If you look in tools:::startDynamicHelp you can see how 
it is set up; you could duplicate that setup as a temporary workaround. 
  You might be better off to build R with static help instead.  What is 
the application where you want to be able to give out links?  Perhaps we 
could consult an environment variable or option() to choose the port 
instead of leaving it completely random.

The reason it is random is the worry that multiple R instances on the 
same machine might collide.  All processes on the machine see the same 
ports.
