You're in luck. Maybe. I tested the following:
<property name="$${foo}" value="foo" />
<echo>${${foo}}</echo>
and sure enough, it doesn't work. This is not so much
because it's no doable as it is because Ant's property
parsing mechanisms don't know any better than to match
the first encountered closing brace. Running from
Ant's svn trunk with the 'props' sandbox antlib,
however, you can install the nested property expander:
<propertyhelper>
<nested xmlns="antlib:org.apache.ant.props" />
</propertyhelper>
This causes the original test to work. The caveat
(beyond the fact that this is only available in an
unreleased version of Ant) is that if property 'foo'
were defined, ${${foo}} would resolve to the expansion
of the expansion of the value of foo. Actually it
should be possible to get around this by using
${$${foo}}, but there seems to be something preventing
this. I'll look into that.
