Howdy all!
Sorry about the delay in responding to the last couple of comments - been very busy with work, as well as the fact that I had a hard time locating this post after its 'relocation'...

I had thought that maybe it had been removed due to my shenannigans, but here it is. Thanks to Schneum and Jarryd for the encouraging comments - hopefully the outcome and 'findings' of this article will be of some use to you both. BTW Schneum, from what I have gathered about E. spathulata, it is an arid climate tree which originates in the dry, dead centre of Oz - I don't know how you will go trying to keep such a tree in your climate, but I suppose it can't hurt to try.
The next installment of 'Eucalyptus as Bonsai' will be about pruning, and I hope to get at least some info up sometime over the weekend, including a pictorial guide to the branch selection and 'pruning for shape and ramification' on the project Angophora above (pictured today in the attachment).
Please bear with me and stay tuned.
Thanks.
FlyBri.
