I can see that a solution based on PEP makes listing your reminders a
matter of checking some well-known node. But, maybe I just misread your
message, why would you use an ad-hoc command for adding reminders
instead of PEP's publish mechanism?

groupchats the reminder shall be sent to the room's bare JID.
I'll try to sum up the feedback received up to now. I wanted to send

* a way of retrieving current reminders must be provided
* not using IQ stanzas but, probably, ad-hoc commands (now also maybe PEP?)
* use the more common <body> element for the reminder's text instead of

localtime and the timezone indication. I think this can be worth
Any feedback would be appreciated.
