I would suggest breaking this project into the two logically seperate 
pieces.

If this is a windows DLL, make yourself a COM or DCOM object in VB or 
VC++, then call that COM object from inside PHP.  The COM object will be 
able to do the tweaky stuff with networks, scanning, etc.  Put all your 
business logic there - scan fila A and put it into folder B based on 
patient ID C.  Alternatively, you can just make a command line 
application that does it in any language you wish, and call it with 
'exec' from PHP.

Lets face it... you COULD do all this stuff with just PHP, but this 
isn't its strength, and would be bleeding edge, and probably not too 
stable... altho it would be noble to try  ;)    Mashing everything into 
one layer also makes it harder to maintain.
