OK, I've managed to get the SLR Pod to work as a mini tripod on a flat table by splaying the legs out as wide as they will go and leaving no room for them to bend and collapse. This works OK with 30D, flash, grip and 17-85 lens but there is still a problem. The pod can only support this setup if the weight is centred over the upright part of the pod. If I try to tilt the camera more than just a fraction, forwards especially, the centre column cannot support the leverage of the load puling forward so the whole thing just collapses forward.
I also tried removing the grip and the flash and that does allow a greater degree of tilt before the support collapses but you need to be careful as once the friction lets go it is not a gradual slide but a rapid collapse until the lens hits something firm.
I've added a few pictures to my Gorilla Pod album showing the successful tripod use, upright with flash and grip attached, and angled with the camera and lens alone.

I do have a suspicion that over time the Pod will loosen up a bit so what may work OK now may not work in the future. As it is the SLR Pod is a nice little device but just a bit limited. If it was my money and I wanted a more trustworthy and future proof solution I think I'd go for the Zoom Pod rather than the SLR Pod.
