Topic: Twitter alike Website-Application

I would like to build a twitter alike website for internal company use.
I heard it can be done easily through ruby on rails open source.
I just need guidance about the same:

Limited user login-registration as it is for internal use only (Blocked for others)
160 characters sharing limit (link should be automatically converted live active)
online offline option with sending message & attachment.

Feedback and suggestions are most welcome.
