Chris,
as Burton said as of today we only have one listener for both sFlow and NetFlow. This will definitively needs to be changed in future releases.
Also note that sFlow support has been coded a few years ago and as I currently don't have access to sFlow traffic, it is likely that the current implementation is poor. If you have suggestions etc. please let us know.
Cheers, Luca

Basically, there is just one listener - for all sflow input. So while there
could be multiple sources, the data will get comingled into a single ntop
virtual NIC. For most people, that's what they really want - a consolidated
network picture.
To change that to multiple virtual NICs you'll have to hack the code in sflowPlugin.com. It's certainly doable - contact me off list if you're interested in sponsoring the work.

Subject: [Ntop] Multiple sFlow interfaces?
Hi,
I'm beginning the process of deploying Ntop for key interfaces throughout my network. My original idea was to deploy one Ntop box per interface and naming them according to what they're monitoring, but that adds up to a lot of machines. In some cases I'll just put multiple NICs in a box to consolidate them to fewer machines.
But in some cases it's more practical to use sFlow rather than a mirrored
port. But to do this using one Ntop box, I need to figure out how to
configure and (hopefully) uniquely name multiple sFlow virtual interfaces,
running multiple sFlow plugins listening to different ports. So far I've
been unable to find any discussion about how/if this might be
accomplished.
In other words (in case I garbled the above), when a user clicks on "Switch NICs" they might see something like this:
Available Network Interfaces:
*Eth0 *sFlow - Router 1 *sFlow - Router 2
Any ideas/resources?
Thanks,
Chris
