This may have changed by now as I gather from the comments it's all pretty
new, but a few months ago I had a look at these I/O functions and would have
liked to use them. When I looked at the fdevopen() function it appears to
malloc a little bit of memory, which then requires all the dynamic memory
library which all adds to the foot print and took up too much FLASH in my
Mega8 so I used something else.

If a usage combination that did not require dynamic memory was available,
more potential use could be made of these functions.
