How to notify users without sending emails?

[satlive]

Due to heavy spamming, many IAP greylist smtp server sending emails to lists of people.

SatLive! currently provides an RSS flux for notifying users but they are not all happy with that.

One specific solution does exist for Apple/Safari fans: there is a notification system which can be used to notify users of new resources on the web site.

There is probably an alternatives for Google/Android/Chrome. Not sure about Windows.

Any ideas welcome.

I can specify ifttt.com that if an new item happens on the RSS flux of SATLive, then it should send me an android notification.

It's not necessary an android notification, a lot of actions are possible to trigger :
