You could always hire a shader programmer

.
I think our community is an attractive part of the A7 package, and so users shouldn't be restricted from posting here. Even users who haven't gotten their hands on it yet will want to be able to ask questions.
The licensed users are much less likely to browse the forums available to the unlicensed users, I think, and thus unlicensed users won't get as much out of the forums.
IMHO, we just need a way to encourage people asking questions to accompany their questions with their version number and edition, because as new features come out those details are relevant anyway.

EDIT/PS: It's quite impressive that you write shaders without a shader-supporting edition!
