Best way to use LimeLM in cloudAnswered

Hi,

I want to check the possibility to use the LimeLM to validate if a key is active in the cloud environment where many instances of an EXE (Linux, or Windows) can run at the same time, with the same key valid on your server-side for example. 

The solution should be light and provide reliable validation of the key. 

Do you provide this in a C++ library, if yes how to implement such a workflow?

Thank you.
