Contributing Ruby language support

Hi,

I'd like to start working on having proper Ruby language support in
CEDET. I have read the documentation and the current code in contrib,
but before I start I'd like to know if someone is already working on
this and decide on:

- should I start anew? seems like things in contrib might have issues
  with future maintainance[1], I'd rather avoid that if possible;
- what papers would I need to sign for my contribution to avoid the
  issue currently faced by things in contrib?
- would it be better to start with an elpa package instead of creating
  the support as part of CEDET?
