Just out of curiosity I tried whether it is possible to run limesurvey on my asus nexus 7 tabloid under android. And indeed: it is incredibly simple. I just installed ksweb (a webserver for android), including php and mysql, downloaded limesurvey, changed the permission of one directory, and the installation of limesurvey works. No rooting of other fuzz, just in a few minutes.
I won't use it, but that makes it possible to run limesurvey on a tabloid without internet connection.
