Yes, and no. There's a new-er application called ConfBridge() which
will let you attempt to do conferencing without depending on a
kernel-based timer. I think you need to jump to the 1.6.2 tree to get
the application, and there isn't much documentation in the world yet.
I attempted to write some up at:

If somebody knows more about ConfBridge() than I do, please feel free
to update the wiki on voip-info.

If you're using tradational MeetMe(), you still need some kind of
kernel module, whether it's dahdi_dummy or the appropriate kernel
module for a real Digium card.
