I've got the code and tests done at this point, but wanted to inquire about the best approach for the XML namespace. The DescribeInstanceTypes call is Eucalyptus specific and the namespace looks like this: http://pastebin.com/LxapvzAg. The call was introduced in version 3.3.0 so I don't want to hard set the API version to 3.4.1 which I'm currently doing. The Euca init function currently looks like this:

def _init_(self, key, secret=None, secure=True, host=None,
path=None, port=None):
"""
@inherits: :class:`EC2NodeDriver._init_`

:param path: The host where the API can be reached.
:type path: ``str``
"""
super(EucNodeDriver, self)._init_(key, secret, secure, host, port)
if path is None:
path = '/services/Eucalyptus'
self.path = path
self.EUCA_API_VERSION = '3.4.1'
self.EUCA_NAMESPACE = 'http://msgs.eucalyptus.com/%s' % (self.EUCA_API_VERSION)

Commit 773cd3d1541ae364eb9d88f7590c1e4b56579508 in branch refs/heads/trunk from Chris DeRamus

LIBCLOUD-516: Add list_size() support into Eucalyptus for cluster versions >= 3.3.0. In this version Eucalyptus introduced the DescribeInstanceTypes call which is specific to EUCA and is not AWS compatible. This call requires a different XML namespace.

Closes #249.
