Not sure what you mean by "user limitation" in this context.
Do you mean, for example, an upper bound on the number of concurrent
sessions which could be served?

Whatever you have in mind here, I'm guessing it violates the
OSD.  For example, placing an upper bound on concurrent sessions
discriminates against large, commercial sites, and thus violates
OSD #6.  So, your proposed license would be allowable under Apache 2.0,
which allows relicensing derivatives on more restrictive terms, but not
open source.
