real-time looping by software?

[Antonio Loro <antonio_loro@yahoo.ca>]

Question:
For looping in real-time, is a hardware looper the way
to go, or can you do the job with a software looper? 
Seems that software has more flexibility, but is
probably less user-friendly in a real-time situation. 
Not to mention, I don't even know if it works in a
real-time context.  
thanks
