These are the categories and descriptors that I have come up with based on research and comments/suggestions from forum/discussion group members:
ÂÂÂ
1. Free Services (Fully Subsidized)
- Services provided by volunteers and/or by paid staff / consultants
- Direct and indirect costs of running the program that provide the technology assistance services are totally subsidized by the service providers, and/or by foundations / funders, grants, etc.
- Includes for-profit companies and organizations that provide "pro bono" technology assistance and support services.
ÂÂÂ
2. Subscription Fee Services (No Subsidies)
- Services are provided by volunteers and/or by paid staff / consultants.
- The subscribers share all the direct and indirect costs of running the program that provides the technology assistance services.
- May also be combined with a Fee Based service.
ÂÂÂ
3. Subscription Fee Services (Partially Subsidized)
- Services (at generally discounted rates) are provided by volunteers and/or by paid staff / consultants
- Part of the direct and indirect costs of running the program that provides the technology assistance service are shared by the subscribers and the other portion of the direct and indirect costs are subsidized by foundations / funders, grants, etc.
- May also be combined with a Fee Based service
- Examples: Geographically based programs like NPower, Information Technology Resource Center (ITRC), CompuMentor and nonprofit management centers based at colleges and universities like the Bayer Center at Robert Morris University.
- Includes for-profit technology companies and organizations that provide services and/or products at a reduced (nonprofit) rate, e.g. Microsoft, Cisco, via TechSoup Stock.
ÂÂÂ
4. Fee Based Services (No Subsidies)
- Each service is provided by volunteers and/or by paid staff / consultants.
- Service purchasers share all direct and indirect costs of running the program that provides the technology assistance service.
- May also be combined with a Subscription Based service.
ÂÂÂ
5. Fee Based Services (Partially Subsidized)
- Each service (at generally discounted rates) is provided by volunteers and/or by paid staff / consultants.
- Part of the direct and indirect costs of running the program that provides the technology assistance service are shared by the service purchasers and the other portion of the direct and indirect costs are subsidized by foundations / funders, grants, etc.
 - May also be combined with a Subscription Based service.

ÂÂÂ
There are also "hybrid" organizations that involve some free and paid services and various combinations of volunteers, paid staff and paid consultants. Overhead costs can also be "hybridized" where there is some subsidized support and some fee-based or subscription-based support.

how do these NTAPs relate?
Great list Dom! I wonder how the following models are best captured. They each fit in the cost based model you listed, but the strength of these models look at costs in different ways than you describe, or they focus on non-cost issues.
"Riders": These are individual consultants generally serving a very localized geography, providing a wide variety of both technology skills and organizational development requirements for adopting/sustaining technology. Because riders have stonger ties to the local community the serve outside of their technology work, they can be very effective in forging relationships and partnerships in the community for technology assistance. Riders are often (not always) working with grant funding to help subsidize the work. Global Eriders, London Advice Services Alliance, LINC Project are examples.
There are also technology collectives. Examples include Tech Underground, NPOTechs, Graphic Alliance and Free Geek. The model here also has a focus on cost, drawing folks together to provide peer support and subsidized/low cost services. Often the overhead of a typical NTAP is reduced, as many collectives are not 501c3, share only minimal common expenses (website, common phone line), and pursue projects individually or in groups guided by individual consultant contracts.
Some thoughts...
