I have a GorillaPod 'Focus' that works quite well. I use it as a 'just in case' tripod, and as long as you do not need a heavy zoom (eg 70-200) it works quite well. The biggest problem of course is height. The smaller 'Zoom' model was not rigid enough for my camera, and sagged under the weight even though the specs said it should have been ok.
I also have a Manfrotto 190 carbon fibre 4-section tripod for hiking. With a decent capacity head it weighs in at 1.8Kg and can take most lens up to about 400mm. It is not mini, but it is small enough to easily attach to the backpack, although the weight can be very apparent when hiking in the mountains.
What I really want is a 10mm TS lens to put on a EOS-M or u4/3 camera...
