Well yes, sort of... but more indirectly. 
@bambukah 's SuperHive is much more flexible than WordPress... It's custom hosted so there is a lot more flexibility with libraries and extensions. The ECC signing and verifying stuff in PHP is great for SuperHive... and that's what's been missing for PHP and Hive I think. 
@mahdiyari just (like hours ago!!!) released a new PHP library that does so much great stuff: @mahdiyari/hive-php-a-real-php-library-for-hive , including signing, verifying, and pretty much all the Hive API operations: and that is AWESOME in so many ways!! It should make work go much faster for any PHP project using Hive!!
So much good stuff!!!
