diference betwen hobbit and bb

Hi
Im working with hobbit and bb at the same time!!!

but now im thinking of change.
I ´d like to use only hobbit clients .
My question is ..
what is the diference betwen bb and hobbit?
i think that using hobbit I will be able to configure many monitors
using only the server part , insted the ext scripts.
for example  scripts in the server part like oracle, cpu, memory,
disk, tomcat,....

On the other hand, my server is a BB one, I´ll need to change it?
regards
