Kitchen-vagrant and providers besides virtual box?

I have some things I’m playing with and would really rather not have to
write providers for both vagrant and test-kitchen. Any plans to have
kitchen-vagrant support providers besides virtualbox? I can take a look at
it, but didn’t want to step on any one else’s work or do something that
would never get merged. test kitchen drivers are easy enough to write, so
it’s not the end of the world If I have to go that way.
