How difficult would it be to make ds_select_domain(set, alg) accept a pseudo variable for the "set" argument?  I would like to map the $rU to a specific dispatcher set via a database table.  I suppose i could just hard code three or four sets with a conditional if() statement, but I would prefer to make it a little more dyanimc.

Correct me if I am wrong in my assumption that ds_select_domain() doesn't accept pseudo variables.

Thanks.
