We actually integrate with PagerDuty and a bunch of other services already (users can submit integrations too) :-)

Existing integrations: http://try.crashlytics.com/integrations/

Submit integrations using: https://github.com/crashlytics/crashlytics-services

The only thing those integrations do is handle the existing Crashlytics-defined alerts. I'm not allowed to define my own alerts.
