NOXT is not a fork of NXT, NOXT is an asset over the nxt network and can be used with nxt wallet like any other nxt asset.

Asset:
"In financial accounting, an asset is an economic resource. Anything tangible or intangible that is capable of being owned or controlled to produce value and that is held to have positive economic value is considered an asset. Simply stated, assets represent value of ownership that can be converted into cash (although cash itself is also considered an asset)."

NXT and supernet are those who make it so easy to create an asset.
NOXT is not trying to compete with nxt nor supernet(which is a dividend paying nxt asset).

NOXT will represent the value of 14 utilities related to NOXT network and will be used to pay for those services.

EDIT: After the utilities paper will be released it will be much clearer
