If anyone would be interested in collaborating on a Perl module using Moose to access the vCloud API, please let me know.
Have you seen the vCloud module here? http://search.cpan.org/~bennie/VMware-vCloud-v2.04/lib/VMware/API/vCloud.pm
Yes, I have but it is not sufficiently comprehensive for my needs. I am working on something designed from the ground-up to support the entire API. More similar to the way the official Java SDK works.
If you need help testing, I can definitely lend a hand.
I'd be interested, though my time is a little short at the moment. If you don't mind, I'd like to loop in with you and see how much time I have to work with you on the project.
