Again, Beem is fantastic :) Best Jabber client on the Android, at least that I've tried. Seems to be far more well-written too, though I'm judging mainly by power usage and other behaviour. I haven't gotten into the source much (yet).
Notifications that repeat. For options, I would expect the option to repeat notifications, as well as how frequently they should be repeated (e.g.: once a minute, once ever five minutes, etc.). I'd think a reasonable set of options would be 1m, 5m, 10m, 30m, 60m.
Merci encore :)
