...but in this case the purchaser is prohibited by network/agency policy
from implementing the solution. A low vision user in the department of
widgets may convince their management chain to upgrade to a version of
software that is more accessible...this chain would include the employee's
supervisor and the EEO staff. After the software has been 'purchased' or
downloaded the network management staff says that the software cannot be
installed because it does not conform to the Agency's IT infrastructure.

I would think that a recommendation from the Web/Software Subcommittee to
the Access Board along the lines: "When user agents have been identified
that improve the access to web or software content for people with
disabilities, these user agents will be made available at the request of
the user."

Tom,

We have that problem generally - any purchaser can potentially decide
that they don't want to upgrade to something new, even if that new thing
is more accessible. There is nothing special here about the web &
graphics magnification.
