This may be because nano tries to do some operations on that "file"
which aren't implemented in owfs. Remember these aren't real files, but
rather an interface to an userland device driver.

It may be because you are reading a cached value on the http server. Try
reading the /uncached directory instead (just prefix anything which
should be new with /uncached).

Sorry, not available. None of the language bindings are using them yet.
A pity.
The best you can do is reading the whole EEPROM contents once, make a
copy of that blob, change the values you want to change and rewrite.
