Unfortunately, there's no timeframe available, yet.
It's a work in progress but there has not been any clue when something will be there.

If you are as impatient as I am 
then you can play in the meantime with my Emergency recoryd plugin and the tvbrowser.org integration - with this you get at least a way to programm timers remotely from a PC or via the ugly hacked webif I did for it
Search for the er6.0.zip kit
But it will not be devleoped any further, I just did it to "motivate" the WebIF developers at little bit and find out what is possible at the moment ...
It has an english readme and is actually relatively small and trivial
(just uses a hacked Webserver from 3c5x9 to get the commands and a shell script to do the jobs)
have fun
