It depends
Jae,
It really depends on the size of the T-hangar. I had a Pitts S-1 and a Citabria in a small T (39' wide). The Pitts fit under the wing of the Citabria, but to get the Citabria out, you had to push the Pitts out first. Here in Livermore you see all sorts of off sharing arrangements. The high-wing low-wing combo is generally ideal for sharing, but again it really depends on what type of plane(s) and what size hangar. Most high wings have struts which will get in the way, which can make sharing difficult.
As Mike said, you could probably fit two 2-place RV's in a small/medium sized T-hangar, but I doubt the -10, with its ~32' span, would fit with much of anything else unless the hangar were fairly large.
One more thing to keep in mind... sharing sometimes forces you to move one airplane to get another one out. If the airplane you are moving is heavy, or the person moving it careless, sharing can be more trouble than it is worth. Just my $.02.
