Dunno' if it will do what you want, but you could add
an *instance method* to return the value of the class
variable; a probe can then have a button you can push
to sample the class variable ... but it won't give you
a running picture of it.  If you absolutely need a
running picture of it, the best approach is probably to
design a special one off object, of which you will have
only one instance, which will have this variable as an
instance var (and will thus be probe-able); the 
instances who want access to it must use methods on
this object to get at it (or you can tweak the objc
scoping directives so exteral objects could get at this
particular var directly, to avoid the messaging
overhead: then the "object" in question is really just
a probe-able wrapper for an application global variable...).

Isn't Swarm fun?
