This is an old post, but I thought I would reply with some of my personal experiences with the Excelsior NET degree. I have only three years of commercial nuke experience so bear this in mind.
Working as an Engineer - I have spoken with engineering managers and supervisors about working in the engineering departments. The technology degree is generally sufficient to be hired on as an engineer. However, some sites told me that I would be an engineering analyst and not a full engineer. So basically do the same job, but get paid less.
Getting the FE/PE - The requirements for the FE are state dependent. For example, I used to live in MN where they would not let me take the FE because my degree did not have enough theory courses. In other states, such as NY where I live now, it is acceptable to have a technology degree and get a FE/PE.
Graduate School - For the brick and mortar schools that I have taken courses at and been accepted into their engineering programs, I was required to take additional undergraduate coursework to make up for the deficiencies in my education. For reference purposes this was the University of St. Thomas in MN and Syracuse University in NY. They did not care whether I took the courses a their school or not. Syracuse (where I currently attend) is kinda cool I think because they do not charge me for the extra courses they are requiring me to take.
Getting a Job Elsewhere - Hmmm... I imagine each place would be different, but some of the places that I have been interested wanted a ABET/EAC degree or a PE license. With the technology degree it would have been very difficult to get hired on as an engineer.
My recommendation - It depends on what type of job you want. If you would like to go engineering then I would strongly recommend getting a full engineering (ABET/EAC) degree. If you are more interested in operations or maintenance, then the technology degree is sufficient.
If you happen to read this post again I hope my answers helped a bit.
