There are libraries about which do some of the work, but they all differ in 
functionality. Someone needs to pull all the features from each together into 
a single mid-level library.

I ended up re-writing everything in user space from scratch for my company's 
applications. Unfortunately this kinda precludes me from writing the above 
mid-level library.
