Joel,

Thanks for that.  Unfortunately it doesn't work for me.
I get lots of errors like the following

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/e2mmap.rb:152: 
warning: already initialized constant UnrecognizedSwitch
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/e2mmap.rb:152:

/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/e2mmap.rb:152:

However, I googled "IRB.start_session" and found some other interesting 
post and replies (all by you I think!); and I can see other things are 
possible.
I'm going to look at this again tomorrow.

Thanks

William
