I think any NAS vendor will be supportive of implementing the DSLF choosen authentication methoed for IP Sessions, if it is DHCP Auth or PANA or something else :)
The reason I asked the question is that if it's pretty much all the same to the vendors, and it would solve the problem, then it would be expedient to go with the PANA solution. The reason it would be expedient is that support for the DHCP option in the Internet Area meeting was weak, and I suspect that of all the people who raised their hands supporting it (e.g., me), a significant percentage would have raised their hands in support of PANA as well. So you could get a strong consensus really easily.
When I asked about this yesterday, Richard said that the reason for choosing DHCP over PANA is that fewer elements in the network have to change, but my superficial understanding of PANA suggests to me that this is not actually the case. It seems to me that PANA can traverse essentially the same path that DHCP relay packets traverse, given that you're going to have to make a change on the BRAS anyway.
As I say, I'm not an expert in PANA, so I may have missed something, but this is my naive understanding of the situation. And again, as I say, I'm not a strong proponent of PANA - I'm just suggesting that we do what is expedient, and will work, rather than fighting a pitched battle for an alternative that in the final analysis probably isn't a better choice, and fundamentally does pretty much the same thing.
