Distributed means "processor on the VIP does the hard work vs. the RSP".
Since a 7206 VXR is as/faster than the processor on the VIP, it's
possible that it can drive as many lines on a PA-MC-8T1 as on a a
VIP with a PA-MC-CT3.
Also, read the fine print, just because X is supported in distributed
mode now, doesn't mean that Y hasn't been for a while or Z ever will
be. 8-(
