Invoke GemRunner with the appropriate ['--list','--remote','etc...'] options.

For examples, look at GemInstaller:

http://geminstaller.rubyforge.org/svn/trunk/lib/geminstaller/gem_list_checker.rb

...which calls:
http://geminstaller.rubyforge.org/svn/trunk/lib/geminstaller/gem_command_manager.rb
(see GemCommandManager#list_remote_gem)

Could probably be improved, I have to do manual parsing of results.
An option to return a data structure would be better.
