I evidentially missed a couple posts here, but :-)...

Dug into iTablet (not itunes :-)) a bit and got something to work.

Randomly selected the itunes button (intuitive my arse ;-) and changed the settings for what it is supposed to do with:

/home/user/vftest

-rwxr-xr-x 1 root root 59 Jan 19 12:42 vftest

The contents of which are:

/usr/bin/flite "This is a long test to see if this works"

And work it does :-)!

Now to try to figure out how to make those icons into something useful. Even text would be more useful, I think.
