umm...unless i'm missing something, and the test i ran somehow worked for 
unbeknown reasons, i would have to say this exactly what i have done. there 
may be some flaw in the design that i have overlooked, but this is the simple 
contruct: when a file is required, the location of that file being required 
is added to the load path. thus any subsequent requires from within that 
require and (requires within those requires) will be findable without 
specifiying the path relative to the running process.

ah, the use of caller is nice! i'll have to think about its use in my 
solution. very nice solution. short and sweet. the only problem i see with it 
is that it can't be used inplace of require, which for me defeats part of the 
purpose.
