>> "Is there a reporting tool available within LimeLM/wyday/wybuild te report on total number of licenses activated vs not, when it was activated, lifespan of a license, licenses about to expire, etc?"
We plan to make getting this data easier, and more visual. Right now you can get it using the advanced search feature in LimeLM.
>> "Also, is anyone aware of any out of the box tools that exist to create an integration with salesforce.com other that pinging the API directly?"
We don't have any pre-written modules for Salesforce, but you can use the LimeLM web API to intergrade with any 3rd party service.
