I have been able to convince my CEO to donate some money towards development of an APNS module for OpenFire. It sounds like the guys from ProcessOne are willing to lend some code or help (see links below). This module will obviously be an attractive thing for companies with iPhones.
I understand that the module would need to be compiled with the dev’s Apple dev account, but we are prepared to do this to support iPhones.
If you are interested in developing this code and offering it back to the community we would love to donate some $ your way. Send me an email and we can chat - Paulc@orionhealth.com
