[cisco-voip] Cisco Unified Presence deployment question

[JA Colmenares]

We will eventually go all CISCO VOIP in our company. However, at this point we are urged of a corporate solution for instant messaging (IM)(availability, federation, logging, centralized control of users, etc). We have been planning to roll out Microsoft Office communication server(OCS) and later integrate it with CISCO presence, however we were asked why we shoulddo that if CISCO Presence would do IM just like OCS and the integration is cleaner.
I like the idea if going with CISCO presence instead of OCS. However, we are not ready for VOIP yet and we need the IM functionality. 
My questions are
1-  Is it possible to deploy Cisco Unified Presence by itself? So we would just start with the Presence server then we can later integrate it with Cisco Communication Manager and Unity? 
2- How does Presence works on the licensing side?

Thanks
Juan
