This is a good idea!

But this "offset" is not standard for file-like objects.

In this case I'd suggest your class to inherit from io.RawIOBase,
and follow its interface.

Here you'd simply have to implement write(), override writable() to return True,
and implement seek() and tell() just by keeping an internal ._offset member.
