I am delighted to hear that you want to work on integration with
openNebula, it seems like a very project.
I am not sure what you are asking though: do you want us to add an ANY
parameter or do you want to experiment with optional parameters
(possibly including ANY) yourself? If the latter, the answer is go right
on ahead, the project is open source :-) .
Adding ANY parameter, as I am sure you realize, is a very controversial
thing to do. We do have plans to accommodate diverse lease terms but
more a-la WS-Agreement where there is some structure to it. Before we do
that though, we plan to expose more extensibility plugins on the
backend. All this won't happen immediately of course and while you can
look for the new plugins in the next release sometime in August, the new
lease structure will probably happen after your summer project has
