With the significant amount of time and capital that Albright invested in his products & services, I'd say it's a safe bet that both of these companies will be around for a long time.
I visited SegPay.com yesterday to check them out & from what I see there, looks like there's plans for affiliate management program.
On the face of it, it seems possible that SegPay's affiliate management program would probably be using the NATS software and this seems to possibly become a more affordable option than leasing NATS and using a separate biller as primary, which in the end will likely increase SegPay's market share.
Will they be around in Jan 2009...

Do the math.
