Ask HN: OpenCV and Php Facedetect. Is there another option than self hosting?

hello! for a web app i will need facedetection software. after some research i found opencv (http://opencv.willowgarage.com/) and a php extension (http://www.xarg.org/project/php-facedetect/) that creates a wrapper for opencv. my problem is that my hosting company does not install such extensions on my virtual server. do you know any other options than a root server (which i would have to administer, update, secure,...)? thanks a lot for your help guys, you´re great! martin
