   Interesting!  So Zaptel does have native TDMoE capabilities.

   Can anyone comment on successes or failures they've had in using these?
Most of the feedback I've heard even on high-end TDMoE gear has been very
lukewarm.

   Also, what about density?  Has anyone tried putting substantially more 
than one quad-span T1 card in an Asterisk box, repeated a couple of times
and clustered together with some level of TDMoE?

   Of course, even if you can stack a PC to the brim with quad-T1 cards and 
expect it to actually work, there is the pervasive problem of the fact 
that it still can't compare with something as relatively cheap -- and 
exponentially more featureful -- as a TNT, which can process multiple DS3s 
and serve as a fairly high-volume, high-density media gateway.  How to
compete with that when you can't even take DS3s?
