[Ironruby-core] How could I get RPC in iron ruby?

Just out of curiosity: What's the process for making an ironruby port of
something like Nokogiri?

I looked at a blog
post<http://blog.headius.com/2010/04/nokogiri-java-port-help-us-finish-it.html>by
one of the people working on the JRuby port and it looks pretty
involved,
but essentially, to port it you would just implement all the
"attach_functions" in libxml.rb in .NET?


--c
