Nop once you have the low lever functions there are no problems,
in the matter of fact its very easy for PIC and not so easy for PC :)

The code for Dallas 1-Wire is available, look at the common PIC
pointers on the net and you find it,

no need to use any ionterface chip, on PIC and pullup (optional
protection) is enough

Which one? Stamps are too slow by himself but there is a
simple add on hardware for 1-wire to stamp interface.

Other PIC basic variants should be fast enough. (Compilers)
So MEL  Basic Compiler asd FED Compiler (A pseudo compiler
actually) should do it.
