No I don't think so - there is no .desktop associated with the 
krubypluginfactory except the one you give it. I cc'd my reply to your last 
mail to the plasma development list, but nobody has replied yet. So I'm still 
not sure what the versions should be and in which .desktop files.

You need to use the plasmapkg tool to install the applet (in the parent 
directory of tiger):

$ plasmapkg --install tiger --type plasmoid

And it will put it under your ~/.kde4 directory.

And yours! No problem, it's very interesting to get feedback. We'll try and 
get this stuff better documented with some more examples, at Akademy in a 
couple of weeks, as the Plasma devs will be there and will be able to help. 
I'll try and see if I can get the tiger working ok with the current Plasma in 
trunk as soon as I can.
